Abstract

Abstract
Purpose: This split-mouth study aimed to study peri-implant tissue health changes between conventional nylon inserts and Retention.Sil600 (RS600) as a polyvinylsiloxane inserts for mandibular implant overdentures.
Materials and methods: Eighteen edentulous patients received two intra-foraminal mandibular implants. Locator abutments were attached, with nylon inserts on one side and RS600 on the other. Modified plaque index (mPI), gingival index (GI), and modified bleeding index (mBI) were assessed at 6 months (T1) and 12 months (T2) post-loading.
Results: Both insert types showed statistically significant increases in mPI, GI, and mBI from T1 to T2 (p<0.01). For nylon inserts, mPI increased from 1.04±0.45 to 1.83±0.45, GI from 1.06±0.42 to 1.02±0.38, and mBI from 0.79±0.34 to 0.94±0.35. For RS600 inserts, mPI increased from 0.83±0.3 to 1.61±0.36, GI from 1.81±0.37 to 1.92±0.36, and mBI from 1.2±0.44 to 1.7±0.45. No significant differences were observed between nylon and RS600 inserts at either time point for any of the measured indices.
Conclusion: Over a one-year period, both nylon and RS600 inserts exhibited similar peri-implant tissue health changes. RS600 may be considered a viable alternative to conventional nylon inserts for mandibular implant overdentures.
