Radiographic and Clinical Evaluation In Bar

Minia University20 enrolled

Overview

the aim of this study was to assess the marginal bone loss and soft tissue outcomes of milled and selective laser melted cobalt chromium bar retaining implant mandibular overdenture. Materials and method: twenty completely edentulous patients received new conventional complete dentures. Two implants were placed at mandibular canine areas, patients were randomly allocated into two equal groups: milled co-cr bar group and selective laser melted bar group. Marginal bone loss, modified plaque index (mPI), probing depth (PD) and modified gingival index (mGI) were evaluated at base line, 6 and 12 months follow up visits.
