应用不翻瓣技术进行后牙区种植义齿修复的临床体会
Clinical observation on dental implant surgery with flapless technique in posterior area.
摘要
Abstract
Objective: To summarize clinical experience of dental implant surgery with flapless technique.Method:53 patients, 26 men and 27 women,with an average age of 47.4±12.3 years,received flapless implant operation to restore 90 missing teeth in posterior area.By using a preoperative CT scan based three-dimensional reconstruction analysis,available length, width and height of the bone in edentulous ridge were measured carefully.All the patients underwent flapless implant surgery and some of operations aided with surgical guides.Finally the implants were introduced and their initial stability was checked.This was followed by immediate CT scan to perform a thorough examination on the placement,positioning, depth,angulation, and hex-orientation of the implant, and on the intactness of the sinus membrane and mandibular nerve.After osseointegration, the corresponding restoration were finished and followed-up.Result: 53 patients with flapless implant surgery were successful implantation of 90 implants without complications such as perforation of maxillary sinus mucosa, mandibular nerve damage, bone perforation etc.Every implants were in good position.The average time of operations was (17.4±5.8)min.Postoperative swelling and pain were in mild degree.86 implants were restored successfully and followed up for 3 to 10 months.Conclusion: Most patients with missing teeth in posterior area are suitable for dental implant surgery with flapless technique.It was helpful to choose tissue punch whose diameter was slightly larger than that of implant.To allow proper seating of the healing abutment, bone profiler was used to shape the coronal aspect of the crestal bone surrounding the implants.关键词
