“…Regarding the guided group, the average deviations were 0.85 ± 0.38 mm (range: 0.42–1.51 mm) for the coronal deviation, 0.93 ± 0.34 mm (range: 0.64–1.72 mm) for the apical deviation, and 3.11 ± 1.55° (range: 0.66–4.95°) for the angular deviation (Table ). Although no previous study assessed 3D deviations regarding computer‐guided immediate implant surgery in the anterior maxilla, studies in partially edentulous zones using tooth‐supported stereolithographic guides showed similar results when compared with the present study (Ersoy, Turkyilmaz, Ozan, & McGlumphy, ; Noharet et al, ; Ozan, Turkyilmaz, Ersoy, McGlumphy, & Rosenstiel, ; Van Assche, Steenberghe, Quirynen, & Jacobs, ; Vermeulen, ). Regarding the freehand group, it is difficult to compare our results to previously published data due to different methodologies used in these studies (Table ) (Gillot et al, ; Van de Velde et al, ; Vercruyssen et al, ).…”

Objective To compare the accuracy of computer‐guided surgery and freehand surgery on flapless immediate implant placement (IIP) in the anterior maxilla. Material and Methods In this split‐mouth design, 24 maxillary incisors in eight human cadaver heads were randomly divided into two groups: computer‐guided surgery (n = 12) and freehand surgery (n = 12). Preoperatively, cone‐beam computed tomography (CBCT) scans were acquired, and all implants were planned with a software (Blue Sky Plan3). Then, two types of surgeries were performed. To assess any differences in position, the postoperative CBCT was subsequently matched with the preoperative planning. For all the implants, the angular, global, depth, bucco‐lingual, and mesio‐distal deviations between the virtual and actual implant positions were measured. Results A significant lower mean angular deviation (3.11 ± 1.55°, range: 0.66–4.95, p = 0.002) and the global deviation at both coronal (0.85 ± 0.38 mm, range: 0.42–1.51, p = 0.004) and apical levels (0.93 ± 0.34 mm, range: 0.64–1.72, p < 0.001) were observed in the guided group when compared to the freehand group (6.78 ± 3.31°, range: 3.08–14.98; 1.43 ± 0.49 mm, range: 0.65–2.31, and 2.2 ± 0.79 mm, range: 1.01–4.02). However, the accuracy of these two approaches was similar for the depth (p = 0.366). In the buccal direction, the mean deviations of both groups showed a general tendency of implants to be positioned facially, occurring more in implants of the freehand group. Conclusion In flapless IIP, computer‐guided surgery showed superior accuracy than freehand surgery in transferring the implant position from the planning. However, even with the help of a guide, the final fixture position tends to shift toward a facial direction.

“…2,3 The precision guide incorporated into the surgical template allows the clinician to place the implant in the planned position more accurately than when using a non-CAD/CAM surgical guide. 4 Even though high precision technologies are used in such processes, studies have shown that some linear and angular deviations between the planned and placed implants can be expected. 5–12 However, the effect of the clinician’s level of experience on the accuracy of implant placement with a computer-guided surgery protocol has not been reported.…”

Statement of Problem Even though high precision technologies have been used in computer-guided implant surgery, studies have shown that linear and angular deviations between the planned and placed implants can be expected. Purpose The purpose of this study was to evaluate the effect of operator experience on the accuracy of implant placement with a computer-guided surgery protocol. Material and Methods Ten surgically experienced and 10 surgically inexperienced operators participated in this study. Each operator placed 1 dental implant (Replace Select) on the partially edentulous mandibular model that had been planned with software by following a computer-guided surgery (NobelGuide) protocol. Three-dimensional information of the planned and placed implants were then superimposed. The horizontal and vertical linear deviations at both the apex and platform levels and the angular deviation were measured and compared between the experienced and inexperienced groups with the independent t test with Bonferroni adjustment (α=.01). The magnitude and direction of the horizontal deviations were also measured and recorded. Results No significant differences were found in the angular and linear deviations between the 2 groups (P>.01). Although not statistically significant (P>.01), the amount of vertical deviation in the coronal direction of the implants placed by the inexperienced operators was about twice that placed by the experienced operators. Overall, buccal apical deviations were most frequent and of the highest magnitude. Conclusion When a computer-guided protocol was used, the accuracy of the vertical dimension (depth of implant placement) was most influenced by the operator’s level of experience.

“…pacientes clinicamente comprometidos e ansiosos, podem se beneficiar muito com a utilização desse protocolo cirúrgico 5,6,8,[11][12][13] . Entre as vantagens para os pacientes, ressaltam-se a natureza minimamente invasiva desse tipo de procedimento, a precisão do posicionamento dos implantes cirurgicamente instalados, a previsibilidade em longo prazo, o menor desconforto pós-cirúrgico e a redução do tempo dispensado na cirurgia e na reabilitação protéti-ca 1,12,14,16 .…”

“…Todo esse contexto permite uma melhor previsibilidade de tratamento, um maior controle dos riscos, obtendo informações mais precisas da anatomia do paciente 2 . A cirurgia guiada de implante melhora a qualidade tanto do procedimento cirúrgico quanto dos resultados restauradores, permitindo uma reabilitação segura e previsível em comparação com a cirurgia convencional [10][11][12][13][14][15] .

IntroduçãoA quantidade e a qualidade do tecido ósseo remanescente deixaram de ser o fator primordial no planejamento cirúrgico para instalação de implantes osseointegráveis 1 . O planejamento reverso tendo como objetivo final a resolução protética é essencial para reabilitações sobre implantes com estética e função adequadas. Um planejamento pré-operatório preciso, tanto para instalação do implante quanto para confecção da restauração protética, é um pré-requisito fundamental para o sucesso da reabilitação oral de pacientes com implantes osseointegráveis 1 .
