Customized Abutment Height and Mucosal Thickness Influence Peri-Implant Bone Stability: Study

The study findings were as follows:

• The study revealed that the most significant marginal bone loss occurred immediately after surgery up to restoration placement.

• Implants with abutment heights and vertical mucosal thickness less than 3 mm experienced more substantial initial bone loss.

• Bone loss stabilized over time, and in some cases, marginal bone recovery was observed by the 12-month follow-up.

• Average loss of 0.84 mm observed in cases with mucosal thickness < 3 mm.

• Bone levels stabilized with average marginal bone loss ranging from 0.05 mm to 0.21 mm between follow-up intervals.

• Abutments < 3 mm showed greater initial bone loss compared to > 3 mm abutments.

Researchers emphasize the critical role of abutment height and mucosal thickness in preserving bone around dental implants. The findings underscore the need for precise treatment planning to optimize peri-implant tissue response. In conclusion, this study highlights that customized abutment height and adequate mucosal thickness are pivotal in mitigating peri-implant bone loss.
