The efficacy of flapless implant surgery on soft-tissue profile comparing immediate loading implants to delayed loading implants: A comparative clinical study

Abstract

Aims and ObjectivesTo assess the efficacy of flapless implant surgery on soft-tissue profile and to compare the clinical outcomes of flapless implant therapy on immediate loading (IL) implants to delayed loading (DL) implants.Materials and MethodsThe study sample consisted of 20 patients who were partially edentulous in the anterior maxillary region. They were divided into two groups. In group I (IL) 10 implants were placed and immediately provisionalized and restored with a metal ceramic crown on the 14th day. In group II (DL) 10 implants were placed and loaded after 4 months. Single-piece implants were used for the IL group and two-piece implants were used for the DL group. All soft tissue parameters i.e., modified plaque index (mPI), modified bleeding index (mBI), papillary index (PPI), marginal level of soft tissue (ML) and width of keratinized mucosa (WKM) were recorded at baseline, Day 60, Day 120 and Day 180.Results:The success rate in group I was found to be 80%, which was lower than the success rate in group II which was found to be 90%. On comparison, there is no statistically significant difference in success rate between the two study groups. There was no statistically significant difference between the groups over time in parameters like mPI, mBI, ML and WKM. The mean PPI score in group II showed a significant increase from when compared to group I.Conclusion:The results of this study indicated that flapless implant surgery using either immediately loading implants or DL implants, demonstrate enhancement of implant esthetics.
