| Objective: To investigate the feasibility of non-submerged immediate dental implant with gingival flap and bone augmentation in anterior dental region,open up a new way of clinical anterior dental region immediate implant and bone augmentation.Methods: 45 patients of anterior teeth without reservation value were selected.All of the diseased teeth had bone defects.The teeth were minimally invasive extraction under local anesthesia.The angular gingival incision was applied in the labial side of the tooth fossa,and the labial gingival flap was opened to expose the labial alveolar bone adequately.Then the palatal mucoperiosteum was properly isolated to reveal the palatal alveolar crest.Thorough curettage was used for the tooth fossa,and the tooth fossa was flushed with saline.Differential mode cavity preparation was used to prepare the planting pit.A total of 50 implants were immediately implanted into planting fossa and healing abutments were installed on the implant.Then,the bone defect area was filled with bone meal and the bone surface covered with absorbable collagen membrane.Results: All 50 implants were successfully achieved non submerged immediate dental implant with gingival flap and bone augmentation.All of the implants had good initial stability after implantation.6-8 months after surgery,all gums and soft tissue cuffs were healthy and well formed.All 45 patients had significant outline aesthetics and red and white aesthetic effects,and were satisfied with the effect of implant restoration.Conclusions: Non-submerged immediate dental implant with gingival flap and bone augmentation in anterior dental region is an effective treatment,and this operation requires only 1 operation to complete the dental implant implantation,bone augmentation and implant above soft tissue forming.This method can preserve the normal gingival contour of the implant,and has a bright red aesthetic effect. |
