Abstract:
BACKGROUND: Mis Seven implant has become more and more popular in oral implant restoration, and the clinical application in dentate-deficient patients remains to be studied. OBJECTIVE: To explore the short-term effects of the Mis Seven implant system on fixed restorations in dentition loss. METHODS: Nineteen patients undergoing fixed dental prostheses with the Mis Seven system due to dentition loss at the Department of Implants of the Stomatological Hospital of Guangzhou Medical University between April 2015 and December 2017 were included. Three patients had missing maxillary and maxillary dentition and unilateral maxillary teeth. Six patients were loss of maxillary dentition, and there were 10 cases of unilateral mandibular dentition missing. The total dental implants were 134. All cases were implanted and fixed for one stage. Clinical examination, alveolar bone and inter-implant image performance and post-load repair effect at 6, 12 and 24 months of follow-up were used as evaluation indicators. RESULTS AND CONCLUSION: (1) In 134 implants, failure was in 2 cases due to surrounding tissue infection. The success rate of before implant restoration was 98.51％, and the success rate after repair was 100％. (2) The stability of dentition of 19 patients was good, showing good occlusion. No mechanical complications or biological complications occurred. The stability of the restoration was 100％. (3) The vertical absorption of bone tissue around all implants was less than 0.2 mm at 6, 12, 24 months after repair, suggesting that the implant has no obvious edge bone resorption. The gingival tissues around all implants were healthy, and no unhealed inflammation or hyperkeratosis appeared. (4) These results imply that the Mis Seven system in the dentition defect fixation exhibits good short-term clinical results.
