Abstract:
Objective This study aimed to evaluate the clinical outcomes of immediate implantation of single maxil-lary central incisor and explore factors affecting post-implant bone volume.Methods Clinical data and imaging records from pre-surgery,the day of surgery,and 6 months post-surgery of 100 patients(100 implants)with non-salvageable maxillary central incisors who underwent immediate implantation were collected.Bone thickness at the cervical,middle,and apical regions of the implant's labial and palatal sides were measured immediately post-surgery and at 6 months,and bone volume changes were observed.A regression analysis model was used to assess predictive factors for labial and pal-atal bone plate thickness.Results At 6 months post-surgery,the labial bone thicknesses at the cervical,middle,and api-cal regions were 2.35,2.29,and 3.28 mm,respectively,and those of the palatal side were 0.00,2.40,and 6.05 mm,re-spectively.The cervical region had the highest alveolar crest collapse rates,with 32.87%on the labial side and 62.20%on the palatal side.The regression model indicated that factors influencing the thickness of bone at the cervical labial side of the implant included initial bone thickness,the implant center to adjacent tooth center angle,implant diameter,and the type of implant closure(P<0.05).The initial bone thickness on the palatal side was the sole predictor for bone thickness on the palatal side(P<0.05).Conclusion Immediate implantation of single maxillary central incisors yields effective clinical results.The thickness of new bone around the implant is influenced by multiple factors.A comprehensive consideration of these factors in the plan-ning of immediate implantation is necessary to achieve optimal therapeutic outcomes.
