ABSTRACT
PURPOSE:
To explore the effect of preformed titanium mesh combined with concentrated growth factor (CGF) membrane on implant restoration of insufficient bone mass in the anterior teeth.METHODS:
A total of 62 patients with insufficient bone mass in the anterior teeth who visited the hospital from January 2017 to February 2020 were selected, and they were divided into experimental group(n=31) and control group (n=31) according to computer digital table method. Both groups of patients used implant restoration. In the control group, the bone defect area was covered with a preformed titanium mesh after implant restoration, while in the experimental group, the bone defect area was covered with a preformed titanium mesh and CGF membrane after implant restoration. After 12 months of follow-up, the success rate of the two groups was counted. Alveolar ridge height, bone increment, alveolar bone density, bone thickness, pink aesthetic index (PES) and complications 6 months after surgery were compared between the two groups. SPSS 19.0 software package was used for statistical analysis.RESULTS:
During the 12-month follow-up, the implantation success rate in both groups was 100%, and there was no implant loosening or dropping. There was no significant difference in the height of the alveolar ridge between the two groups before operation(P>0.05). The postoperative alveolar ridge elevation and bone increment in the experimental group were significantly higher than those in the control group(P<0.05). There was no significant difference in alveolar bone density and bone thickness between the two groups before operation(P>0.05). The alveolar bone density and bone thickness of the two groups 6 and 12 months after operation were significantly lower than those before operation (P<0.05). The alveolar bone mineral density 6 months after operation in both groups was significantly lower than that 12 months after operation(P<0.05), and the alveolar bone thickness 6 months after operation in both groups was significantly higher than that at 12 months after operation (P<0.05). The alveolar bone density and bone thickness of the experimental group 6 and 12 months after operation were significantly higher than those in the control group(P<0.05). The postoperative PES score of the experimental group was significantly higher than that of the control group(P<0.05). There was no significant difference in the total incidence of complications between the two groups 6 months after operation(P>0.05).CONCLUSIONS:
Preformed titanium mesh combined with CGF membrane is used in implant restorations for patients with insufficient bone mass in the anterior teeth, and the effect is definite. It can enhance the cosmetic effect of implant restorations, improve postoperative bone metabolism, and is safe and reliable.
