Background In previous studies, immediate implant placement in molar sites has been widely applied. Purpose To study the clinical effect and feasibility of immediate implant placement combined with maxillary sinus floor elevation utilizing the transalveolar approach and nonsubmerged healing for failing teeth in the maxillary molar area. Material and Methods Patients who required implantation surgry to replace a failing tooth in the maxilla molar region were selected. Patients were randomized into two groups: immediate implant placement combined with maxillary sinus floor elevation utilizing the transalveolar approach and nonsubmerged healing (test group) or delayed implant placement combined with maxillary sinus floor elevation utilizing the transalveolar approach and nonsubmerged healing (control group). The outcome criteria were the success rates of implants, Cone Beam Computer Tomography (CBCT) data and results of the subjective satisfaction survey performed with a visual analog scale (VAS). Results All implants had good initial stability after implantation. The survival rate of implants was 100% at 1‐year follow‐up. At the time of permanent restoration, the differences in average horizontal shrinkage of alveolar bone (W1) on the buccal side between the test group (0.65 ± 0.12 mm) and the control group (1.23 ± 0.32 mm) were statistically significant (P < .0001); however, no statistically significant difference (P = .515) was observed on the palatal side (0.3 ± 0.10 mm vs 0.28 ± 0.08 mm). The difference in vertical resorption of alveolar bone (H1) on the buccal side between the test group (0.60 ± 0.18 mm) and the control group (1.53 ± 0.19 mm) was statistically significant (P < .0001), but no statistically significant difference (P = .190) in the reduction of palatal alveolar bone (0.24 ± 0.12 mm vs 0.29 ± 0.13 mm) was observed. After 1‐year loading, no statistically significant difference (P > .05) in vertical or horizontal changes (W2, H2) were identified in the test group or control group. Patient satisfaction in both groups was similar (8.36 ± 1.01 vs 8.14 ± 1.35), and the difference between groups was not statistically significant (P = .638). Conclusion Immediate implant placement combined with maxillary sinus floor elevation utilizing the transalveolar approach and nonsubmerged healing is feasible for the maxillary molar area, and the clinical effect is satisfactory.

BackgroundClinical studies on immediate implant placement for a single anterior maxillary tooth with a facial bone wall defect are rarely reported.ObjectiveTo study the clinical outcomes of immediate implant placement combined with flap surgery, guided bone regeneration and non‐submerged healing for a single anterior maxillary tooth with a facial bone wall defect.Materials and MethodsForty‐five patients with a single failing tooth in the anterior maxillary region showing indications for extraction combined with a facial bone wall defect were treated by means of immediate implant placement combined with flap surgery, guided bone regeneration and non‐submerged healing. During this study, the implant survival rate, soft and hard tissue dimension changes, pink aesthetic score (PAS), and patient aesthetic satisfaction were assessed at 1, 6, and 12 months post‐operatively.ResultsAt 12 months post‐operatively, the survival rate of 45 implants was 100%. Mesial/distal papillary level reduction and midfacial soft tissue recession were measured as 0.53, 0.41, and 0.31 mm, respectively. The thickness of facial bone reduction measured by cone beam computed tomography was 0.94, 0.80, 0.85, 0.82, 0.45, and 0.41 mm at 6 different sites around the implant. The mean PAS and patient aesthetic satisfaction were determined to be 10.58% and 93%, respectively.ConclusionsThe proposed surgical procedure is a valuable treatment strategy as assessed by preliminary clinical outcomes.
