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.

Abstract This article describes a newly designed surgical template that was used to facilitate dental implant placement. The implants were planned to function by loading them immediately. A case report describing the device and the benefits of its use for a patient with an edentulous mandible is presented. Four implants were placed in the anterior region of the mandible to support an immediately fixed prosthesis. Clinical and radiographic analyses were conducted postoperatively to evaluate bone loss and peri-implant soft-tissue healing. The salutary results demonstrated the positive value of this therapeutic approach and presented the advantages of shorter treatment times, fewer patient visits, lower costs, and elimination of secondary surgical procedures.

The Cost

Application of surgical stents for implant placement via guided flapless surgery is increasing. However, high cost, need for some professional machines, and not taking into account the soft-tissue parameters have limited their application. We sought to design and introduce a technique named in-office guided implant placement (iGIP) to decrease the cost by using available devices in office and enhance the applicability of surgical stents. A customized surgical stent was fabricated based on prosthetic, soft- and hard-tissue parameters by taking into account the amount of available bone (using the computed tomographic [CT] data), soft-tissue thickness and contour (using a composite-covered radiographic stent), and position of the final crown (by diagnostic cast wax up and marking the final crown position with composite). The efficacy of iGIP, in terms of the accuracy of the three-dimensional position of the implant placed in the study cast and in patient's mouth, was confirmed by direct observation and postoperative CT. The iGIP can enhance implant placement in the prosthetically desired position in various types of edentulism. Using this technique minimizes the risk of unwanted consequences, as the soft-tissue thickness and contour are taken into account when fabricating a surgical stent.

Soft Tissue Changes

Abstract Background The aim of this study was to assess the mid-facial soft tissue changes induced by a micro-implant-supported maxillary skeletal expander in late adolescents and young adults by cone-beam computerized tomography and the correlations between hard and soft tissue changes after expansion with maxillary skeletal expander.Subjects and methods Twenty patients with maxillary transverse deficiency treated with maxillary skeletal expander were selected. Cone-beam computerized tomography images taken before and after expansion were superimposed to measure the changes in soft and hard tissue landmarks.Results Anterior nasal spine, posterior nasal spine, and alveolar bone width were significantly increased after expansion with maxillary skeletal expander (p < 0.05). The average lateral movement of the cheek points was 1.13 ± 0.33 mm (left) and 1.41 ± 0.39 mm (right), while that of the alar curvature points was 1.07 ± 0.72 mm (left) and 1.06 ± 0.68 (right) (p < 0.05). The average forward displacement of the cheek points was 0.42 ± 0.66 mm (left) and 0.60 ± 0.58 mm (right), whereas that of the alar curvature points was 0.80 ± 0.67 mm (left) and 0.68 ± 0.56 mm (right) side (p < 0.05). The average downward movement of the subnasale was 0.40 ± 0.37 mm (p < 0.05). The changes in cheek points and alar curvature points on both sides significantly correlated with hard-tissue changes (p < 0.05).Conclusions Maxillary expansion using maxillary skeletal expander resulted in significant lateral and forward movement of soft tissues of the cheek and alar curvature points on both sides and correlated with the maxillary suture opening at the anterior and posterior nasal spines.
