Short-term effect comparison of a modified socket shield technique and conventional flapless immediate implant and immediate restoration in maxillary aesthetic area

Abstract

Abstract:

BACKGROUND: The conventional shield technique can reduce the absorption of labial fasciculate bone after immediate implantation of anterior teeth, but it is highly demanded by the operator. When implants are implanted, it is easy to loosen the remaining teeth on the labial side, resulting in failure of the operation.

OBJECTIVE: To evaluate the clinical effects of a modified socket shield technique for immediate implant and immediate restoration and flapless immediate implant and immediate restoration in maxillary aesthetic area.

METHODS: Sixty patients were randomly chosen with failing tooth from September 2016 to August 2017 in Department of Stomatology in Affiliated Hospital of Binzhou Medical College. The samples included 33 males and 27 females, aged from 20 to 81 years. There were 38 cases of central incisor and 22 cases of lateral incisor. The patients were randomly divided into two groups. The 30 patients in the experimental group received a modified socket shield technique for immediate implant and immediate restoration. The 30 patients in the control group received conventional flapless immediate implant and immediate restoration. During return visit after 1 year, the retention rate of the implant and pink esthetic score were recorded; the buccal bone thicknesses of the implant neck and roots 2, 4 mm were observed by cone beam computed tomography; and the patient satisfaction was analyzed. The study was approved by the Medical Ethics Committee of the Affiliated Hospital of Binzhou Medical College (Hospital Ethics Approval Number: 2019-LW-025).

RESULTS AND CONCLUSION: (1) The survival rate of both groups was 100%. (2) One year after operation, the pink esthetic score of the experimental group was higher than the preoperative score and that in the control group (P < 0.05). The pink esthetic score of the control group was lower 1 year after surgery than preoperative score (P < 0.05). (3) One year after operation, the buccal bone thickness loss of the implant neck and roots 2, 4 mm in the experimental group was lower than that in the control group (P < 0.05). (4) The satisfaction rate of the experimental group was higher than that in the control group (P < 0.05). (5) The results showed that the modified socket shield technique used for immediate implant and immediate restoration can maintain the buccal bone thickness and improve the aesthetic effect.
