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. Procedure. However, precautions are advised and should be taken with these patients before and during the procedure to prevent bleeding-related adverse events that may occur. Evidence from these SRs indicates increased risk of implant failure among smokers. Indications and Contraindications. 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. A relative contraindication indicates that caution should be exercised and it is likely that the benefit of the procedure outweighs the risks involved. Indications, Guidelines and Risk Factors of Early and Immediate Implant Placement with Root-analog Implants: A Literature Review Dr. med. However, elective surgery should not be performed if hemostasis is not possible. These SRs evaluated 113 primary studies and more than 28,000 dental implants over a 20-year period. The contraceptive implant is a small, flexible 40mm plastic rod fitted by a trained healthcare professional, usually a doctor or a nurse. 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. Glycemic control has also been evaluated. 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. Smoking is directly correlated with educational status. Evidence from these SRs indicate that there is increased risk of marginal bone loss, periimplantitis, and implant failure (odds ratios [ORs] ranging from 1.7 [CI, 1.23–2.79]; 95% CI, 1.12–8.15) with chronic periodontitis. INDICATIONS Generally any edentulous area can be an indication for dental implants. Hyperbaric oxygen is a consideration when a dental implant is planned for a region that has received greater than 50 Gy; however, consensus is lacking on the need for this treatment. Risk seems to increase when the radiotherapy dose is more than 50 Gy ; however, most SRs did not analyze the dose received as a confounder. In this article, our opinions focus on systematic reviews (SRs) of the literature because this is the highest level of evidence. Evidence from these SRs indicates that there is no difference in dental implant survival in patients with or without osteoporosis. After the indication, the precautions and contraindications should be considered as balancing components of the decision-making and informed consent process. Ten primary studies appeared in both data sets. Risk for periimplantitis 1.89, (95% CI, 1.31–2.46. Antiresorptives are given either orally or intravenously. 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. Hispanic and Latino people, African Americans, American Indians, Pacific Islanders, and Asian Americans are at higher risk for diabetes than white people. The findings support about a 2-fold higher risk for those who are bruxers versus nonbruxers. 2009). Abnormalities in platelet count and function can also contribute to abnormal bleeding during or after implant surgery. There are no SRs available on RANKL inhibitors or antiangiogenic medications as of this date. In the Moraschini and colleagues SR, 14 primary studies published between 2000 and 2015 were evaluated. Dental implants temporary contraindication: maxillary sinus lowering of the maxillary sinus. These agents show various potencies. Experienced implantologist is able to assess the degree of surgical intervention, enabling the creation of new conditions for the implantation. The investigators did not consider the glycemic control levels, and reported that survival rates of diabetics were similar to those of healthy controls (95.1 vs 97%, 97.2 vs 95%, 92 vs 93.2%, and 97 vs 98.8%) in 4 primary studies that had a follow-up of more than 1 year; however, 2 studies showed a shorter survival period, which yielded an RR of 4.8 and 2.75 for implant failure in diabetic patients. Hardback Cover. There were 4 case reports and 5 longitudinal studies. A meta-analysis yielded an overall failure rate risk ratio (RR) of 4.00 (95% confidence interval [CI], 1.79–8.93; P <.001) in patients who had a history of aggressive periodontitis compared with healthy controls. 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. Dentysta i stomatolog Gdańsk.Projekt i wykonanie – Agencja marketingowa MGMedia.eu. Bone resorption following tooth loss often interferes with dental implant placement in a desired position, and requires additional bone augmentation procedures. These patients, in general, received periodontal treatment for several years before implants were placed. Bruxism, a condition in which the patient clenches and grinds the teeth, is a recognized risk factor for implant fracture and failure as a result of abnormal physical force. The increased risk may be caused by compromised bone level; reduced bone quality; immune dysregulation; or concurrent exposures, such as poor oral hygiene, tobacco use, or persistent periodontal pathogens. 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). Indication of implant placement Failure of traditional prosthetic treatment . 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. Prem et. There are 2 SRs on osteoporosis and dental implants. There are few absolute contraindications to dental implant placement.

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. There are 5 SRs on radiation and implant failure. The reference value for platelet count is between 150,000 and 400,000 cells/mm 3 . There are 2 SRs and 1 meta-analysis on bruxism and dental implants that evaluated 38 primary studies over a 15-year period. List the indications and contraindications for dental implants. Like any surgical procedure, however, it requires a surgical intervention. Periodic periodontal maintenance program is documented to be associated with improved implant survival. General indications and contraindications for dental implant treatment. In 2 SRs, implant survival rates in individuals with a history of bisphosphonate use ranged from 95% to 100% versus 99% in healthy individuals with a follow-up period of 4 months to 7.4 years. Abnormal postsurgical hemorrhage may be noticed in mild thrombocytopenia (50,000–100,000 cells/mm 3 ). 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. Diabetes can also hinder the process of osteointegration. 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. Indications and contra-indications for dental implants. 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.

Guided bone regeneration (GBR) techniques: –Lateral augmentation –Split osteotomy – bone splitting –Onlay-plasty –Autogenous monocortical bone augmentation –Sinus-lift . A reference research was carried out on PubMed using the key words “implant” AND (oral OR dental) AND (systemic disease OR medically compromised), in articles published between 1993 and 2013. CChemotherapy (i.e. 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.
