Objective：To introduce a novel ridge preservation technique with micro-titanium plate avoiding the use of bone grafting materials, and evaluate the potential horizontal bone preservation effect of this new technique, applied on single maxillary central incisors after tooth extraction for future implant restoration. Methods: Nine patients (six women and three men), mean age （26.0±5.7） years(from 18 to 34 years) referred to the Department of Oral Implantology, Peking University School and Hospital of Stomotology, were selected and diagnosed with unsalvageable single middle incisor with fine general conditions, no signs of acute local inflammation, no ongoing or previous periodontitis, healthy neighboring teeth and intact buccal bone walls. Tooth extraction, delayed implant placement and implant-supported single crown restoration were selected as treatment plan. The teeth were extracted atraumatically with local anesthesia, followed by a reflection of a minor flap to exposed 2-3 mm of the buccal bone plate. After that, a micro-titanium plate was trimmed and bended to fit the convexity of the labial bone and fixed by two mini pins with intent to support the labial soft tissue. The flap was then repositioned over the micro titanium plate and secured with two single sutures. No bone grafting materials or releasing incisions were needed. The sockets were left to heal without any intention of primary wound closure. Cone-beam computed tomographic (CBCT) scans were obtained before and four months after tooth extraction. Horizontal ridge widths were measured with CBCT software, and the preservation effects were calculated and recorded by the percentage of horizontal ridge alteration. Results: The nine extraction sockets were healed uneventfully. The average socket width before extraction was (7.51±0.48) mm (6.92-7.82 mm). The average alveolar ridge labial-palatal width at the control point of the edentulous area was (6.81±0.44) mm (6.04-7.38 mm) 4 months after tooth extraction, the mean percentage of ridge width preserved was 90.87%±2.91% (87.28%-95.60%). Conclusion: This novel ridge preservation method by the usage of a micro-titanium plate did not interfere with the natural socket healing process, and at the same time, largely preserved the width of alveolar ridge without any bone grafting procedures. Long term results remain to be seen.
