Secondary Healing

Wound dehiscence is the most frequent complication after ridge augmentation and causes postoperative infection, inadequate bone healing, or graft failure. In the oral cavity, conservative treatment for dehiscence is difficult to maintain until secondary healing occurs because of its normal flora, dynamic masticatory muscle movement, and humid environment. This paper reports an effective conservative method using an oral wound dressing material with an omnivec splint and presents three wound dehiscence cases: (1) autogenous tooth bone graft material with a collagen membrane, with dehiscence occurring at postoperative 5 days. (2) Autogenous bone graft covering titanium mesh, with dehiscence occurring at postoperative three weeks. The mesh was removed after 10 weeks with histologic analysis. (3) Autogenous bone and autogenous tooth bone graft covering a titanium mesh, with dehiscence occurring at postoperative 1 week. The exposed titanium mesh was maintained for 6 months after the graft. All cases achieved secondary healing and acceptable outcomes for a dental implant by conservative treatment without infection after the dehiscence after ridge augmentation.

ABSTRACT Calcium sulfate is a biologically compatible osteoconductive graft material that binds underlying bone graft and provide space maintenance. The purpose of this study was to evaluate calcium sulfate as a barrier compared to a collagen membrane for augmentation of a standardized surgically created ridge defect. For this purpose, bilateral extraction of mandibular premolars was performed on six foxhounds (Canis familiaris). Eight weeks later, a standardized osseous ridge defects (24 total) were created using a 6 mm trephine. The study was approved by the Institutional Animal Care and Use Committee (IACUC) at Baylor College of Dentistry. The osseous defects were allocated into three groups (8 defects each): group 1 received autogenous bone graft covered with collagen membrane (CM); group 2 received autogenous bone graft covered with calcium sulfate barrier (CS), and group 3 was used as control and did not receive bone augmentation and was used as control. The animals were sacrificed after 12 weeks following bone augmentation and sites were evaluated histologically for total ridge width, percentage of bone gain and cortical bone thickness. Results All sites exhibited bony fill within the defect. Analysis of variance did not reveal statistically significant difference in the mean total bone gain among CM, CS, and control groups (12.2,11.6, and 11.9) mm2, respectively, p = 0.875. Conclusion Calcium sulfate does not appear to improve bone regeneration in an osseous defect. How to cite this article Heaton ML, Kerns DG, Hallmon WW, Kessler HP, Spears R, Solomon ES, Al-Hashimi I.

ABSTRACT Aim The present work describes a horizontal ridge augmentation in which a titanium mesh was preshaped by adapting it to a stereolithographic model of the patient's jaw that was fabricated from CT scans. Background Guided bone regeneration (GBR) involves covering the augmentation site with a long-lasting barrier to protect it from the invasion of surrounding soft tissues. Among barriers, titanium meshes may provide a successful outcome, but the intraoperatory time needed to shape them is a disadvantage. Case description The 54-year-old patient, missing the right mandibular second bicuspid, first molar, and second molar, had her atrophic ridge augmented with a 30:70 mixture of autogenous bone and equine, enzyme-deantigenic collagenpreserved bone substitute. Two conical implants were inserted concomitantly in the second bicuspid and first molar positions, and the site was protected with the preshaped mesh. Four months later, the titanium mesh was retrieved, a bone sample was collected, and histological and histomorphometric analyses were performed. Provisional and definitive prostheses were then delivered, and follow-up controls were performed for up to 24 months. Conclusion Preshaping the mesh on a model of the patient's mandible shortened the surgical time and enabled faster mesh placement. Two years after surgery, the implants were perfectly functional, and the bone width was stable over time as shown by radiographic controls. Histological analysis of the bone sample showed the heterologous biomaterial to be biocompatible and undergoing advanced remodeling and replacement with newly formed bone. Clinical significance Preshaping a titanium mesh over a stereolithographic model of the patient's jaw allowed for a significant reduction of the intraoperative time and may be therefore, advisable in routine practice.

Different Types

Alveolar ridge augmentation can be completed with various types of bone augmentation materials (autogenous, allograft, xenograft, and alloplast). Currently, autogenous bone is labeled as the “gold standard” because of faster healing times and integration between native and foreign bone. No systematic review has currently determined whether there is a difference in implant success between various bone augmentation materials. The purpose of this article was to systematically review comparative human studies of vertical and horizontal alveolar ridge augmentation comparing different types of bone graft materials (autogenous, allograft, xenograft, and alloplast). A MEDLINE search was conducted under the 3 search concepts of bone augmentation, dental implants, and alveolar ridge augmentation. Studies pertaining to socket grafts or sinus lifts were excluded. Case reports, small case series, and review papers were excluded. A bias assessment tool was applied to the final articles. Overall, 219 articles resulted from the initial search, and 9 articles were included for final analysis. There were no discernible differences in implant success between bone augmentation materials. Generally, patients preferred nonautogenous bone sources as there were fewer hospital days, less pain, and better recovery time. Two articles had industrial support; however, conclusions of whether that support influenced the outcomes could not be determined. Future comparative studies should compare nonautogenous bone sources and have longer follow-up times.

Abstract Background The purpose of this study was to evaluate the volumetric changes in partially edentulous alveolar ridges augmented with customized titanium ridge augmentation matrices (CTRAM), freeze-dried bone allograft, and a resorbable collagen membrane. Methods A pre-surgical cone beam computed tomography (CBCT) scan was obtained for CTRAM design/fabrication and to evaluate pre-surgical ridge dimensions. Ridge augmentation surgery using CTRAM, freeze-dried bone allograft, and a resorbable collagen membrane was performed at each deficient site. Clinical measurements of the area of augmentation were made at the time of CTRAM placement and re-entry, and a 2nd CBCT scan 7 months after graft placement was used for volumetric analysis. Locations of each CTRAM in situ were also compared to their planned positions. Re-entry surgery and implant placement was performed 8 months after CTRAM placement. Results Nine subjects were treated with CTRAM and freeze-dried bone allograft. Four out of the nine patients enrolled (44.4%) experienced premature CTRAM exposure during healing, and in two of these cases, CTRAM were removed early. Early exposure did not result in total graft failure in any case. Mean volumetric bone gain was 85.5 ± 30.9% of planned augmentation volume (61.3 ± 33.6% in subjects with premature CTRAM exposure vs. 104.9% for subjects without premature exposure, p = 0.03). Mean horizontal augmentation (measured clinically) was 3.02 mm, and vertical augmentation 2.86 mm. Mean surgical positional deviation of CTRAM from the planned location was 1.09 mm. Conclusion The use of CTRAM in conjunction with bone graft and a collagen membrane resulted in vertical and horizontal bone gain suitable for implant placement.
