“…This makes it difficult to evaluate how the present results were consistent with other comparable studies. Nevertheless, recent independent studies reported similar results in three-dimensional deviation between virtual planning and final implant positions [10,11,12]. …”

Purpose: To compare virtual planning accuracy of novel computer-assisted, template-based implant placement techniques, which make use of CAD/CAM stereolithographic surgical templates with or without metallic sleeves. Furthermore, to compare open versus closed sleeves for templates without metallic sleeves. Materials and methods: Any partially edentulous patients requiring at least one implant to be placed according to a computer-assisted template-based protocol were enrolled. Patients were randomized according to a parallel group design into two arms: Surgical template with or without metallic sleeves. Three deviation parameters (angular, horizontal, vertical) were defined to evaluate the discrepancy between the planned and placed implant positions. Results: No implants failed, and no complications were experienced. Forty-one implants were placed using surgical templates with metallic sleeves while 49 implants were placed with a surgical template without metallic sleeves. Of these, 16 implants were placed through open sleeves and 33 through closed sleeves. There was a statistically significant difference in angle (p = 0.0212) and in the vertical plan (p = 0.0073) with lower values for implants placed with a surgical template without metallic sleeves. In the test group, close sleeves were more accurate compared with open sleeves in angle (p = 0.0268) and in horizontal plan (p = 0.0477). Conclusion: With the limitations of the present study, surgical templates without metallic sleeves were more accurate in the vertical plan and angle compared to the conventional template with metallic sleeves. Open sleeves should be used with caution in the molar region only in case of reduced interarch space. Further research is needed to confirm these preliminary results.

“…The insertion of dental implants by means of computer‐assisted template‐based surgery is an established method . One of the most important stages for the development of guided implant placement has been the diffusion of 3‐dimensional imaging technique and modern implant planning softwares . The increased demand for dental implants to replace teeth has encouraged advancement in digital technology to improve patients' acceptance and clinical outcomes .…”

Background The insertion of dental implants by means of computer‐assisted template‐based surgery is an established method. Purpose To investigate the accuracy of a newly developed sleeve‐designed template and to evaluate differences between maxillary and mandibular implants as well as anterior versus posterior area. Materials and Methods Any partially edentulous patients requiring at least one implant to be planned on three‐dimensional cone beam computed tomography scan, according to a computer‐assisted template‐based protocol, were consecutively enrolled at two centers. Any potential implant position was considered eligible for the present trial. Outcome measures were: implant failure, complications, and accuracy. Results A total of 39 patients with 119 implants were evaluated. No patients dropped out during the study period (mean follow‐up 12.4 ± 7.1 months). Three implants failed at centre two, whereas, one complication was experienced at centre one (limited access in posterior area). Differences were not statistically significant (P > .05). The mean deviations were 0.53 ± 0.46 mm (range 0.05‐3.38 mm; 95% CI 0.32‐0.48 mm) in the horizontal plan (mesio‐distal); 0.42 ± 0.37 mm (range 0.0‐1.53 mm; 95% CI 0.26‐0.40 mm) in the vertical plan (apico‐coronal); and 1.43 ± 1.98° (range 0.03‐11.8°; 95% CI 0.31‐1.01°) in angle. Differences between centers were compared using the nonparametric Mann‐Whitney U test (P > .05). More accurate results were found for anterior implants in both horizontal plan and angle. Conclusion This study showed good precision in all the parameters measured. The results were thus in a range equal to or better than the mean precision found in numerous clinical trials described in the literature. Posterior implants were less accurate because of the use of open sleeves template.

“…At the same time, the dual acid etched surface of these implants has the potential to accelerate bone healing, as demonstrated by a recent histologic/histomorphometric human study [13]. In modern oral implantology, the presence of an adequate macrostructure (thread design) and microstructure (surface roughness) is considered critical for functional immediate loading [21][22][23]. Finally, new materials (such as composite resins) are now available for the fabrication of fixed full arch mandibular dentures [24,25].…”

is properly cited.Purpose. To present a new intraoral welding technique, which can be used to manufacture screw-retained, mandibular fixed fullarch prostheses. Methods. Over a 4-year period, all patients with complete mandibular edentulism or irreparably compromised mandibular dentition, who will restore the masticatory function with a fixed mandibular prosthesis, were considered for inclusion in this study. The "Ball Welding Bar" (BWB) technique is characterised by smooth prosthetic cylinders, interconnected by means of titanium bars which are adjustable in terms of distance from ball terminals and are inserted in the rotating rings of the cylinders. All the components are welded and self-posing. Results. Forty-two patients (18 males; 24 females; mean age 64.2 ± 6.7 years) were enrolled and 210 fixtures were inserted to support 42 mandibular screw-retained, fixed full-arch prostheses. After two years of loading, 2 fixtures were lost, for an implant survival rate of 97.7%. Five implants suffered from peri-implant mucositis and 3 implants for peri-implantitis. Three of the prostheses (3/42) required repair for fracture (7.1%): the prosthetic success was 92.9%. Conclusions. The BWB technique seems to represent a reliable technique for the fabrication of screw-retained mandibular fixed full-arch prostheses. This study was registered in the ISRCTN register with number ISRCTN71229338.
