ABSTRACT
OBJECTIVES: To compare esthetics at single immediately placed implants with and without soft tissue augmentation.
MATERIAL AND METHODS: Patients with non-restorable maxillary teeth in the esthetic zone were assigned into 2 groups: immediately placed implants with simultaneous vascularized interpositional periosteal connective tissue grafting (VIP-CTG) or non-grafted immediately placed implants (NG). The outcomes included: pink esthetic score (PES), gingival thickness, keratinized tissue width, buccal bone changes, marginal bone loss, pain, and satisfaction.
RESULTS: Eighteen implants were included.At two years the mean value for PES was 12 ± 3.2 for the VIP-CTG and 12.9 ± 1.3 for the NG (p = 0.855). Mucosal thickness and keratinized tissue width showed no statistically significant difference between the two groups (p = 0.253) and (p = 0.931) respectively. Clinically buccal bone showed mean bone loss of 2.03 ± 1.57 mm for VIP-CTG and 1.09 ±1.3 mm for NG (p = 0.247) and radiographically showed 1.67 ± 0.84 mm at the VIP-CTG and 1.16 ± 0.47 mm at the NG (p = 0.118). No statistical significant difference between both groups was demonstrated regarding marginal bone level changes (p = 0.142), pain (p = 0.622) nor satisfaction (p = 0.562) at any time point.
CONCLUSION: Simultaneous soft tissue grafting with immediate implant placement did not provide a more favorable outcome regarding esthetics or alveolar bone preservation effect. Undisturbed healing with the least surgical intervention seems to provide more favorable outcomes.
