Do antibiotics help reduce implant failure? A systematic review

This summary is based on the Cochrane Systematic Review: Interventions for replacing missing teeth: antibiotics at dental implant placement to prevent complications (July 2013) Marco Esposito, Maria Gabriella Grusovin, and Helen V. Worthington         Context Some dental implant failures may be due to bacterial contamination at implant insertion. Infections around biomaterials are difficult to treat, and almost all infected implants have to be removed. In general, antibiotic prophylaxis in surgery is only indicated for patients: At risk of infectious endocarditis; With reduced host-response; When surgery is performed in infected sites; In cases of extensive and prolonged surgical ...

Do sensation differences exist between dental implants and natural teeth?

This summary is based on the article published in Clinical Oral Implant Research: Do sensation differences exist between dental implants and natural teeth? A meta-analysis (November 2014) Nobuaki Higaki, Takaharu Goto, Yuichi Ishida, Megumi Watanabe, Yoritoki Tomotake, Tetsuo Ichikawa   Context Mastication is an essential function for processing foods into a bolus in the oral cavity. 1-3 This behavior is controlled in a coordinated manner by the stomatognathic organs and regulated by the central pattern generator in the brain stem. 4-5 Moreover, the oral sensory-motor system, including periodontal sensation, is thought to affect the oral motor behaviors and to be ...

Does diabetes affect implant failure rates?

This summary is based on the article published in the Journal of Dental Research: Diabetes and oral implant failure: a systematic review (September 2014) B.R. Chrcanovic, T. Albrektsson, and A. Wennerberg Context Dental implant survival is initially dependent on successful osseointegration following placement. As an implant is restored and placed into function, bone remodeling becomes a critical aspect of implant survival in responding to the functional demands placed on the implant restoration and supporting bone. The critical dependence on bone metabolism for implant survival may be heightened in patients with diabetes (1). Diabetic patients have increased frequency of periodontitis and ...

What are the current perspectives on the role of ridge (socket) preservation procedures in dental implant treatment in the aesthetic zone?

This summary is based on the article published in the Australian Dental Journal: Current perspectives on the role of ridge (socket) preservation procedures in dental implant treatment in the aesthetic zone (March 2014) B Kassim, S Ivanovski, N Mattheos      Context Augmentation of the extraction socket (ridge preservation) is increasingly being advocated in anticipation of implant placement. Substantial tissue loss leads to increased difficulty in placing the implant fixture in a prosthodontically suitable position. To facilitate such placement, guided bone regeneration (GBR) procedures (either simultaneous at implant placement or staged as a separate surgical procedure) are often required. Ridge ...

Does the use of antibiotics reduce the frequency of implant failure and post-operative infection?

This summary is based on the article published in the International Journal of Oral and Maxillofacial Surgery: Do antibiotics decrease implant failure and postoperative infections? A systematic review and meta-analysis (January 2014) J. Ata-Ali, F. Ata-Ali, F. Ata-Ali       Context Dental implants are an effective, safe and predictable solution for those who have lost a tooth or teeth due to dental caries, periodontal disease, injury, or other reasons.(1) It is believed that a certain number of early dental implant losses are due to bacterial contamination at implant insertion.(2) It is still debated whether early dental implant failure and ...

How successful are implants for orthodontic anchorage and what are the reasons of their failures?

This summary is based on the article published in Implant Dentistry: Implants for Orthodontic Anchorage: Success Rates and Reasons of Failures (April 2014) Juan C. Rodriguez, DDS, Fernando Suarez, DDS, Hsun-Liang Chan, DDS, MS, Miguel Padial-Molina, DDS, PhD, and Hom-Lay Wang, DDS, MSD, PhD Context In orthodontics, controlled forces are applied in specific directions to move teeth from improper locations into what is considered an “ideal” physiologic/esthetic location. To provide the movement, a steady and strong support known as orthodontic anchor is required. Anchorage, by definition, is a resistance to displacement provided by a static object. The most common anchor used is the patient’s own dentition; however, in some cases, the anchorage is limited or ...

How successful are implants placed in sites of previously failed implants? A systematic review

This summary is based on the article published in Implant Dentistry: Implants Placed in Sites of Previously Failed Implants: A Systematic Review (June 2014) Alessandro Quaranta, DDS, PhD, Vittoria Perrotti, DDS, PhD, Adriano Piattelli, MD, DDS, Matteo Piemontese, MD, DDS, and Maurizio Procaccini, MD, DDS Context Despite the high success rates reported for dental implants,(1, 2) failures requiring implant removal do occur. The overall first year failure rate may vary between 3% and 8%.(3) There are different patient-related reasons to avoid reimplantation, such as additional costs, fear of additional pain, and fear of a second failure4; nevertheless, implant replacement still remains a therapeutical option to be considered. Purpose of the Review The ...
