Effect of Mucosal Thickness and Implant Depth on Crestal Bone Change of Implants

doi:10.13701/j.cnki.kqyxyj.2023.02.010

Abstract

Abstract: Objective: To explore the effect of different implantation depths and gingival thicknesses on bone remodeling around implants. Methods: From January 2018 to June 2020, 78 patients who received single posterior implantation in the Implant Center of Taiyuan Hamony Long Stomatological Hospital were selected. A total of 96 platform-switching implants were implanted. They were divided into two groups according to the thickness of mucosa: thin gingiva group (< 3 mm) and thick gingiva group (≥ 3 mm). Forty-six implants in thin gingiva group were implanted 1.5 mm below the bone level, 50 implants in the thick gingival group were implanted aligning with the bone level. Digital periapical films were taken immediately after implantation and 6 months and 12 months after prostheses delivered. The changes of bone level in the two groups were measured, respectively. Results: There was no significant difference in bone resorption between thin gingiva group and thick gingiva group 6 and 12 months after prostheses delivered (P>0.05). There was no thread exposure in thin gingiva group. Conclusion: The bone level of the implant can be maintained by placing the platform-switching implants into a suitable position under the bone level so as to make up for the lack of soft tissue thickness.
