General indications and contraindications for dental implant treatment. But these are extreme cases. Bisphosphonates have a high affinity for hydroxyapatite crystals and are used to increase bone strength and reduce the risk for fractures. Evidence from a recent SR indicates a higher survival rate of dental implants in irradiated mandible than in irradiated maxilla (OR, 3.67; 95% CI, 2.81–4.79; P <.0001). These SRs evaluated 113 primary studies and more than 28,000 dental implants over a 20-year period. Similar findings are reported by Naujokat and colleagues, who evaluated 22 primary studies in which survival was measured within the first 6 years of placement; however, dental implant failure was observed to be increased in diabetic patients when the observation period was 20 years. Indications for treatment generally are considered when a patient initially presents with a problem or complaint. For this report, risks for dental implant failure have been categorized into local factors, behavioral factors, and medical factors. Radiation therapy is a common component of the cancer treatment of many of these patients. Patients ranging from 17 to 82 years of age received more than 260 dental implants and were followed for 2 to 36 months. Many systemic diseases that are regulated such as diabetes, hypertension, or different types of hormonal imbalance, contrary to popular belief, are not an absolute contraindication to perform dental implant surgery. Osteoporosis is a medical condition characterized by low bone mass associated with imbalances in bone metabolism causing the bone to become brittle and fragile because of a decrease in bone volume and quantity. Readers are cautioned that although SRs provide a high level of evidence for decision making, SRs are not without flaws and some are better than others. A surgical procedure can lead to hemorrhage in patients who have a congenital (hemophilia A – factor VIII deficiency; hemophilia B – factor IX deficiency) or acquired bleeding disorder; however, medical consultation with the patient’s physician and precise treatment planning before the surgical procedure can minimize adverse outcomes. Indications and Contraindications. There are 8 SRs on diabetes that have analyzed 14 to 22 primary studies. Detailing the limitations of SRs is beyond the scope of this article, and the authors do not attempt to analyze the quality of the SR. If so, where is this stated and has this been established by studies in peer revied dental journals or been stated as position papers by dental specialty organizations? The aim of this study was to review the current scientific literature in order to analyse the indications and contraindications of dental implants in medically compromised patients. A precaution indicates that there is ability to prevent or mitigate the adverse event. Findings from this meta-analysis showed no difference in the dental implant failure rate among well-controlled versus poorly controlled diabetics (RR, 0.620; 95% CI, 0.0225–1.705; P = .354). Prem et. www.indiandentalacademy.com 7. Turns of the indications and contraindications, there are many halftones. Accordingly, dental practitioners should be cognizant of the current evidence and review the medical status of each patient before beginning a procedure for dental implant placement in a patient who uses or has received antiresorptive medications. The absolute contraindications are the ones that surgeon should not perform implant surgery in such conditions. Placing a dental implant is an elective procedure that requires consideration for the desires, oral anatomy, potential trauma, and healing capacity of the patient. Diabetes is a well-recognized risk factor for poor wound healing after surgical procedures caused by abnormal glucose blood levels and altered immune response, both of which may contribute to implant failure. Straight abutments indicated for both screw retained and cemented restorations are included. Contra Indications for Dental Implants. Expert opinion suggests that there are few situations or medical conditions that create an absolute contraindication for placing a dental implant. Abnormalities in platelet count and function can also contribute to abnormal bleeding during or after implant surgery. a Not all studies reported the number of implants, cases, or controls. There are few absolute contraindications to dental implant placement. in other cases, pathological formations (cysts, tumors, etc) inside the oro-maxillary-facial area, which shrink or even destroy the necessary bone for implants. Each time before the implantation of the titanium implant our doctors need to check patient’s detailed medical history. Five of the studies were from the Mengal and colleagues author group and 4 studies had been previously evaluated by Al-Zahrani. They […], Klinika stomatologiczna Perfect Smile Clinic, ul. Relative contraindications include cognitive decline, American Society of Anesthesiology Patient Status IV or higher categories, or medical conditions that may jeopardize the life or lifespan of the patient. The follow-up period was up to 11 years. Dental implants serve as artificial roots which can act as supports for the replacements of missing teeth. Here is a non-exhaustive list of the most frequent local, relative and absolute contraindications. Risk for dental implant failure increases in association with (1) past history of periodontal disease, (2) bruxism, (3) smoking, and (4) radiation therapy. Indications and contra-indications for dental implants. A patient is diagnosed with diabetes if the fasting blood glucose is 126 mg/dL or higher, or the hemoglobin A1c is 6.5% or greater. Patients with International Normalized Ratio (INR; prothrombin ratio = patient prothrombin/control prothrombin) value of higher than 3.5 should be referred to their physicians for improved control and, once controlled, considered for treatment in a setting that will provide for good hemostasis. A relative contraindication indicates that caution should be exercised and it is likely that the benefit of the procedure outweighs the risks involved. Contraindications for dental implants. In this article, we shall look at the procedure, indications and contraindications of the contraceptive implant. Together, these factors can lead to implant failure. In case of severe thrombocytopenia, platelet values less than 50,000 cells/mm 3 can complicate implant placement or lead to postoperative hemorrhage. Sample Cases . The rationale of increased risk is not well established; however, the literature suggests that adjacent periodontally involved teeth may contribute to the cause through the transfer of periodontal pathogens from adjacent disease sites to the implant site. Spectrum of risk when considering placement of a dental implant. The findings support about a 2-fold higher risk for those who are bruxers versus nonbruxers. Caveats to consider in the interpretation of these data include that periodontal disease is often associated with confounders (ie, tobacco smoking) and comorbidities (eg, diabetes) and that these factors are not always well controlled for in the SRs published to date. In these studies, the survival rate is reported to be 96% in the osteoporosis group. dental implant contraindications – local causes In the normal local anatomy there are some structures which act as anatomical barriers (the lower alveolar nerve inside the mandibular canal, maxillary sinuses, etc). The anatomic location is also a consideration. It is important for clinicians who are planning dental implants to consider that patients who brux often report morning stiffness or tightness in masticatory muscles, and show wear of the dentition. 1 ). Pterygoid Implant Complications. 228 Color Pages . Here the survival rates for 264 dental implants in 60 patients with aggressive periodontitis were 83.3% to 100%, with a follow-up period ranging from 12 to 120 months. The surgeon must take proper medical history to find out the underlying medical problems of the patient. Dental implants, pathologies and systemic diseases. Also, the SRs reviewed generally showed variability in the definitions in periodontitis and implant failure, loading and follow-up period, details regarding the type and frequency of periodontal treatment provided, and outcome criteria, each of which contribute to difficulty in accurate interpretation of the findings. Osteonecrosis was reported to occur in 78 patients (53 in mandible and 23 in maxilla) who used bisphosphonates, with the highest prevalence in those who had combined use of oral and intravenous bisphosphonates. An absolute contraindication indicates that the procedure could cause a life-threatening event or the risk of the procedure clearly outweighs any possible therapeutic benefit. 2009). 3 Indications and Contraindications. Such a procedure is always carefully explained to the patient during the first visit. The aim of this study was to review the current scientific literature in order to analyse the indications and contraindications of dental implants in medically compromised patients. Dental implants temporary contraindication: maxillary sinus lowering of the maxillary sinus. In total, 1330 implants were placed in 528 bisphosphonate users and 2418 implants were placed in 811 healthy patients. The aim of this study was to review the current scientific literature in order to analyse the indications and contraindications of dental implants in medically compromised patients. interdental problems (implants will be applicable here in order to increase the number of the pillars of the future dental bridge, or a single prosthetic crowns). Although primary stability can be achieved, it is best to initiate guided bone regeneration (GBR) to reconstruct the alveolar ridge to improve success and optimize esthetics, especially in the anterior region. Assessment and Management of the High-Risk Dental Patient with Active Substance Use Disorder, Motivational Communication in Dental Practices, The Use of Botulinum Toxin and Dermal Fillers to Enhance Patients’ Perceived Attractiveness, Evidence-Based Update on Diagnosis and Management of Gingivitis and Periodontitis, Nonrestorative Management of Cavitated and Noncavitated Caries Lesions, Dental Clinics of North America Volume 63 Issue 3, Periodontal disease (aggressive and chronic). Hemorrhage is a potential complication during or after dental implant placement. If necessary, the patient’s medical practitioner should be consulted. The 2014 SR provides a more rigorous study design than the Al-Zahrani SR, with the inclusion of meta-analysis and assessments for heterogeneity, quality, and publication bias. Shi and colleagues evaluated the failure rate of 286 dental implants placed in 252 well-controlled diabetics and 301 dental implants placed in poorly controlled patients reported in 7 primary studies. Data from the de-Freitas and colleagues SR included 8 retrospective studies, 1 prospective study, and 6 case series. The success rate of dental implants dropped considerably when patients smoked more than 10 cigarettes per day. In 12 prospective studies, the investigators evaluated 2825 implants placed in 843 patients with treated periodontitis. In addition, during the first visit, any local restrictions for a proposed procedure for dental implant will be defined. These patients include those categorized as American Society of Anesthesiology patient status IV or higher (eg, oropharyngeal malignancies, recent cerebrovascular accidents and myocardial infarction, uncontrolled or poorly controlled epilepsy, diabetes mellitus or psychiatric illness, risk of osteoradionecrosis, bleeding disorders, profound immunosuppression, drug and alcohol abuse, active cancer chemotherapy and receiving intravenous antiresorptive medication, or conditions that may jeopardize the life or lifespan of the patient). Worldwide, more than 200 million women have osteoporosis and it affects approximately 75 million people in the United States, Japan, and Europe according to the International Osteoporosis Foundation. It is estimated that 37.8 million (15.5%) adults smoke cigarettes every day, and about 15 of every 100 adults aged 18 years or older in the United States smoke cigarettes. The high dose of radiotherapy is also damaging to the adjacent tissues and can result in reduced blood supply to bone, bone sclerosis, and reduced ability of osseous regeneration. Therefore a thorough understanding of the indications and contraindications of implant supported prostheses (intra oral implant) is mandatory for the success of the treatment. Are these absolute contraindications for implants described in any text book? Indications and Contraindications of Dental Implant Therapy. Several decades of experience in dental surgery clearly prove that dental implants provides the patient with much more than just the right support and stability of the prosthesis. The contraceptive implant is a small, flexible 40mm plastic rod fitted by a trained healthcare professional, usually a doctor or a nurse. Unfavourable anatomical conditions (makroglossia). There are few absolute contraindications to dental implant placement. Indication of implant placement Failure of traditional prosthetic treatment . 2004; Wagenberg and Froum 2006; Chen, Beagle, et al. Survival rates of implants in patients without periodontitis ranged from 91.7% to 100% compared with 71% to 100% for patients with treated periodontitis. Endosseous dental implants are titanium fixtures that are placed in edentulous ridges to serve as support for fixed or removable dental prostheses used to restore dentition. There are few absolute contraindications to dental implant placement. Prosthetic Considerations. : Indications for dental implant treatment- A clinician’s point of view latter can complicate the design of fixed and removable restorations. Risk for dental implant failure increases in association with (1) past history of periodontal disease, (2) bruxism, (3) smoking, and (4) radiation therapy. There are 5 SRs on radiation and implant failure. Indications, contraindications, and limitations of immediate implant placement are presented and presented. Nevertheless, increased periimplant bone loss was observed in patients with osteoporosis. The most important classification concerns the absolute-relative contraindications. Any of these conditions bar elective oral surgery, and require judicious monitoring by the physician as … The relationship between dental implant survival and bisphosphonate use has been documented in 5 SRs that evaluated more than 4500 dental implants. In the 9 retrospective studies, 8102 implants were evaluated in 2086 patients. With all the popularity of dental restoration using dental implantation, as well as an increasing number of patients wishing to have a flawless smile and keep their teeth healthy for as long as possible, implantation as a method of treating adentia has strict indications and contraindications. These patients, in general, received periodontal treatment for several years before implants were placed.

These systematic reviews included 18 studies from 2001 to 2017, and examined more than 20,000 dental implants over a period of 1 to 22 years. Bisphosphonates are generally prescribed for osteoporosis as an oral medication or a single annual injection of zoledronic acid. In the context of decision making and dental implants, evidence suggests that 90% to 95% of dental implants are successfully maintained for 10 years and 51.97% to 75.8% survive at 16 to 20 years.
