Introduction: Rehabilitation of the anterior maxilla using dental implants is frequently problematic because of the deficiency of alveolar ridge width. Under certain conditions ridge augmentation with simultaneous implant placement is recommended.
Objectives:To evaluate horizontal augmentation of narrow anterior maxillary alveolar ridge with simultaneous implant placement using Cerabone® with and without platelet rich plasma (PRP).
Materials and Methods:In this study, 14 implants were placed in patients with insufficient alveolar ridge width in the maxillary lateral incisor region. Patients were divided into two groups; In Group “1" Cerabone® only was used as an augmentation material while in Group “2" a mixture of Cerabone® and PRP was used. A collagen membrane was used to cover the grafting material. Postoperative pain was assessed using visual analogue scale. Healing and postoperative edema were evaluated. Cone Beam Computed Tomography (CBCT) was obtained before surgery, immediately postoperatively and after 6 months so that the labial bone width and bone density were evaluated. Osstell was used to evaluate implant stability quotient (ISQ) during surgery and after 6 months.
Results:All implants in both groups were successfully osseointegrated and functionally stable. No significant difference in postoperative pain, edema or wound healing was detected between the two groups. The mean percentage of change in ISQ was superior in Group “2" when compared to Group “1", but statistically there was no significant difference (P=0.898). The labial bone width in Group “2" was significantly higher than that of Group “1" (P=0.002). The mean percentage of change in labial bone density was 57.95% in Group “1" and 112.52% in Group “2" (P=0.848).
Conclusion:Cerabone® can be used effectively for guided bone regeneration around dental implant in narrow maxillary anterior alveolar ridges. Moreover, the addition of PRP has a positive effect on bone regeneration around implants.
