Primary stability achieved during implant surgery and bone loss at recovery in patients of a private dental institution — A retrospective analysis

Abstract

Implant stability plays a critical role for osseointegration, without osseointegration long term success cannot be achieved, primary stability occurs from mechanical attachment with the cortical bone. It is the gold standard for success of implants. This is a descriptive clinical study carried out in saveetha dental college and hospital, Poonamallee, Chennai. All the patients who underwent single or two-unit implant surgery were selected. The study setting was done from university predominantly south Indian populations and data with regard to primary stability at placement, level of the implant with bone, crestal bone loss at stage 2 recovery were retrieved from the digital case sheets. Data were entered using SPSS software, and Chi-square test was used for inferential analysis, with a P-value < 0.05 was said to be statistically significant. The results obtained indicate more implants are placed with primary stability in 30-40 Ncm(49.8%). More frequently placed crestal relation is equi crestal region (84.4%) and crestal bone loss was less than 1-2mm is seen(87.3%) at stage 2 recovery. The results were subjected to statistical chi-square test, and it is observed that primary stability at 30-40 Ncm or greater did not have any significant association with crestal bone loss. An equi crestal placement of the implant was preferred irrespective of implant type.
