Cover Screw vs Healing Abutment on Osseointegration

This randomized split-mouth clinical trial aims to compare the effects of using a cover screw versus a healing abutment on early implant stability and osseointegration. Patients requiring at least two dental implants will receive both interventions in a split-mouth design, with one implant randomly assigned to the cover screw group and the contralateral implant assigned to the healing abutment group. Implant stability will be assessed using resonance frequency analysis (RFA) and Implant Stability Quotient (ISQ) measurements during the healing period.

Feasibility Study on the Application of Bionic Healing Abutments in Implant Impressions

The bionic healing abutment of the group's previous research results has both soft tissue shaping and impression taking functions, realizing the advantages of no need to dismantle the impression, simplifying clinical operation, maintaining soft tissue closure and reducing patient discomfort, responding to the requirements of the new quality productivity. On this basis, this study is intended to explore the accuracy of implant restorative impressions with bionic healing abutment and transfer bar in the impression of membrane material, and with bionic healing abutment and scanning bar in the digital impression in the case of different parts of the missing teeth and different numbers of missing teeth, so as to provide a basis for the application of bionic healing abutment in implant restorative impressions and guidance on the use of the clinic.
