Study design:

Cohort study 

研究目的:

通过比较一期手术伴同期PGBR术的硬组织宽度变化量,探究一期手术同期行PGBR对硬组织的影响及探究影响术后软硬组织宽度变化的其他可能影响因素  

Objectives of Study:

By comparing the hard tissue dimensional changes between primary surgery with concurrent PGBR (Prosthetically Guided Bone Regeneration), this study investigates the impact of performing PGBR concurrently during the primary surgery on hard tissues and explores other potential factors influencing post-operative dimensional changes in both hard and soft tissue
