About

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.

20 participants in 2 patient groups

group 1: milled cobalt chromium bar

Active Comparator group

Description:

10 completely edentulous patients received two implants at canine region bilaterally (3.7mm diameter- 13mm length), within two weeks after surgery (following early loading protocol), an open tray impression technique was made for bar construction which was designed according to randomization patient enrollment

Treatment:

Other: bar retained implant overdenture

group 2: Selective laser melted cobalt chromium bar

Experimental group

Description:
