“…Optimal positioning ensures adequate bone volume surrounding the implant with correct load distribution. Whilst freehand (FH) implant placement has been the standard approach [ 5 , 6 ], the surgical accuracy of this method can be limited. Despite the use of anatomical landmarks or stents, FH surgery relies on good three-dimensional (3D) spatial awareness and high levels of surgical experience to place the dental implant correctly within the limited volume of residual bone [ 7 , 8 ].…”

An increase in the number of implants placed has led to a corresponding increase in the number of complications reported. The complications can vary from restorative complications due to poor placement to damage to collateral structures such as nerves and adjacent teeth. A large majority of these complications can be avoided if the implant has been placed accurately in the optimal position. Therefore, the aim of this in vitro pilot study was to investigate the effect of freehand (FH) and fully guided (FG) surgery on the accuracy of implants placed in close proximity to vital structures such as the inferior alveolar nerve (IAN). Cone-beam computed tomography (CBCT) and intraoral scans of six patients who have had previous dental implants in the posterior mandible were used in this study. The ideal implant position was planned. FG surgical guides were manufactured for each case. In this study, the three-dimensional 3D printed resin models of each of the cases were produced and the implants placed using FG and FH methods on the respective models. The outcome variables of the study, angular deviations were calculated and the distance to the IAN was measured. The mean deviations for the planned position observed were 1.10 mm coronally, 1.88 mm apically with up to 6.3 degrees’ angular deviation for FH surgery. For FG surgical technique the mean deviation was found to be at 0.35 mm coronally, 0.43 mm apically with 0.78 degrees angularly respectively. The maximum deviation from the planned position for the apex of the implant to the IAN was 2.55 mm using FH and 0.63 mm FG. This bench study, within its limitations, demonstrated surgically acceptable accuracy for both FH and FG techniques that would allow safe placement of implants to vital structures such as the IAN when a safety zone of 3 mm is allowed. Nevertheless, a better margin of error was observed for FG surgery with respect to the angular deviation and controlling the distance of the implant to the IAN using R2 Gate® system.

Purpose: The purpose of this study was to evaluate the effect of Desktop scanning protocol on accuracy of guided implant placement in completely edentulous patients.Methodology: Twenty four completely edentulous patients were selected for implant placement. Complete dentures were made for all the patients. Radioopaque markers were added to the dentures to be used as a radiographic stent. A Cone beam CT scan was then made for each patient while wearing the radiographic stent. The patients were then randomly divided into 2 equal groups. In the first group, a CBCT scan was made for the radiographic stent. In the second group, desktop scanning was made for the radiographic stent while being seated on the patient's cast and another scan for the patient's cast. After implant insertion, CBCT scan was made for each patient while wearing the radiographic stent. Superimposition of CBCT scans pre and post implant insertion was made. Deviations between planned and placed implant were measured in the lateral apical, lateral coronal and angular aspects.Results: Non statistically significant difference between radiographic and desktop scanning on implant deviation was observed. Conclusion:within limitation of this study, effect of both scanning protocols on the lateral apical, lateral coronal and angular deviations of placed implants is comparable.

“…CAD-CAM technology [17] has helped in developing minimally invasive surgical techniques guided by intraoral splints [18] or computer-assisted procedures [19][20][21]. Treatments with conventional implants performed under surgical guides have achieved survival rates similar to conventional procedures [22], providing greater accuracy and precision than freehand techniques [23]. On the other hand, due to variations in the position and angulation of implants with respect to the previous computer-assisted planification zygomatic implants, surgical guides have demonstrated to be highly imprecise [18,24].…”

Accuracy of digital planning in zygomatic implants

Background Zygomatic implants have been described as a therapeutic alternative for patients with severe maxillary atrophy in order to avoid bone augmentation procedures. Taking that into account, in these treatments, the key factor is the position of the implant, the virtual surgical planning (VSP) is widespread among most clinicians before surgery on the patient. However, there are no studies which evaluate the clinical relevance of these VSP. The aim of this study is to determine whether digital planning on zygomatic implants has any influence on the implant dimensions and position, even when performing conventional surgery afterwards. Results Fourteen zygomatic implants were placed in four patients. Pre-operative and post-operative helicoidal computed tomography were performed to each patient to allow the comparison between the digital planning and the final position of implants. Tridimensional deviation (TD), mesio-distal deviation (MDD), bucco-palatine deviation (BPD), and apico-coronal deviation (ACD) were evaluated as well as angular deviation (AD). Significative differences in apical TD were observed with a mean of 6.114 ± 4.28 mm (p < 0.05). Regarding implant position, only implants placed in the area of the first right molar reported significant differences (p < 0.05) for ACD. Also, implant length larger than 45 mm showed BPD significative differences (p < 0.05). Conclusions Zygomatic implant surgery is a complex surgical procedure, and although VSP is a useful tool which helps the clinician determine the number and the length of zygomatic implants as well as its proper position, surgical experience is still mandatory.
