A selection of abstracts of clinically relevant papers from other journals. The abstracts on this page have been chosen and edited by Reena Wadia Interproximal contact loss is a common multifactorial implant complication.
This study aimed to determine the prevalence and contributing factors of interproximal contact loss (ICL) between implant restorations and adjacent teeth as well as provide recommendations for prevention and treatment. A literature search on PubMed revealed seven studies showing a high prevalence of ICL between implant prostheses and adjacent teeth. ICL was greater in the mesial aspect compared with the distal. ICL in the maxilla ranged between 18% and 66% versus 37% to 54% in the mandible. ICL might occur as early as three months after prosthetic treatment. Documented possible causes included: tooth migration, crown-related and bone formation/growth-related. The authors explained that the clinical condition will dictate if the implant crown needs to be modified/replaced or the natural tooth restored to re-establish the interproximal contact. Periodic evaluations and the use of screw-retained restorations due to ease of removal is recommended to diagnose and mitigate the problem. An orthodontic retainer or occlusal guard might also help.
