The Influence of Initial Soft Tissue Thickness on Peri‐Implant Bone Remodeling

Abstract

The present study suggests that implants with lower abutments, reflecting the initial gingival thickness, lose more peri-implant bone, possibly by a re-establishment of the biological width.

The prosthetic abutment height can affect marginal bone loss around dental implants

“…16 In the present study, group 3 (with an abutment height of ≥3 mm) showed reduced MBL, although the distance from the alveolar bone crest to the gingival margin would be >4 mm. 16 In the present study, group 3 (with an abutment height of ≥3 mm) showed reduced MBL, although the distance from the alveolar bone crest to the gingival margin would be >4 mm.…”

“…15,16 In the present study, group 1 showed a low success rate and an increased mean MBL. 15,16 In the present study, group 1 showed a low success rate and an increased mean MBL.…”

A randomized controlled clinical trial assessing initial crestal bone remodeling of implants with a different surface roughness

“…21 In the present study, the vertical position of the implant was adapted according to soft tissue thickness and a uniform final abutment of 4 mm height was chosen. After implant placement, an initial bone remodeling occurs resulting in steady-state bone levels after 3 to 6 months.…”

“…Beside the difference in implant surface, the two implants are identical with a thread pitch of 0.6 mm, an integrated platform-shift with a smooth implant bevel, and an internal connection and microthreads on the implant neck. 21 After final implant seating, insertion-torque values were registered on the drill unit (W&H Dentalwerk, Bürmoos, Austria). The implants were placed crestally or subcrestally, taking the soft tissue thickness into account, ensuring a 3-4 mm soft tissue seal ( Figure 1C).…”

A randomized controlled clinical trial to assess crestal bone remodeling of four different implant designs

“…10 Therefore, crestal bone preservation is paramount for implant success. 12,13 Another factor that affects this crestal bone remodeling is the microgap at the implant-abutment junction. This biological phenomenon is referred to as "biological width" and is considered to be a physiological process.…”
