“…However, all investigative procedures reported have been executed in partially edentulous patients with surgical guides entirely docked to the teeth. This is known because accuracy is significantly higher when the model has a dental support rather than a mucosal one (45,(56)(57)(58)(59). In addition, it affects the learning curve demonstrating that the surgeon has more or less familiar with the surgical procedures.…”

SUMMARYPurpose. This study describes the ability to perform a technique for bone regeneration in maxillary posterior deficit (TGSL) without the use of bone grafting materials using a highly minimally invasive protocol. Materials and methods. Sixty six implants have been inserted in the sinus floor of a total of 39 patients through the transcrestal guided sinus lift technique (TGSL). All patients have been followed for at least three years in function. The drilling protocol was adapted on the basis of bone density of each implant site to achieve a torque between 45 and 55 Ncm. Healing titanium abutments tightened to 35 Ncm have been used. A CAD/CAM metal ceramics final prosthetic restoration has been generated a six months after the tissues healing and the provisional functionalization of the occlusion. Survival rate of implants and prostheses, biological and biomechanical complications, changes in marginal bone levels, and total height of alveolar crest bone before and after surgery have been evaluate and measured by the results obtained in this prospective study. It was also measured the periodontal parameters as well as levels of perception of pain by the patient during the entire recovery period.Results. The result of the data of follow-up was 41.96 (24 to 36) months. Cumulative implant survival was 98.53% at 3 years. There were no biological and mechanical complications and there were no prosthetic failures during the whole period of follow-up. The Marginal Bone Loss (MBL) average during the first year of operation was from 0.33 to 0.36 mm, while the 3-year follow-up, the MBL average was 0.51 to 0.29 mm. The average of residual bone height of alveolar ridge before treatment was 6.7 to 1.6 mm (range 5.1 to 9.2 mm), while the average bone height was gained 6,4 -1.6 mm (range 3.2 to 8.1 mm). All patients reported lower pain levels and found to have normal periodontal parameters. Conclusions. This study suggests that the use of guided surgery to perform transcrestal maxillary sinus lift to increase the sub-antral crestal height is a minimally invasive technique of success for the short and medium-term of follow-up, thus avoiding the extended treatment time and reducing the morbidity associated with the lifting of the floor of the maxillary sinus with traditional technique using bone grafting materials. Furthermore, this protocol without the use of graft materials does not vary the final outcome that have demonstrated the presence of newly formed bone around implants offering always predictable results, and giving a further reduction in the costs of the procedure rehabilitation.

“…When an implant placement is planned in clinically challenging cases, several surveying techniques are available, among which Computerised Tomography (CT) has been shown to be among the most precise ones [17]. The two-dimensional representation which is rendered by the printed sections, however, is a limiting factor in interpretation and surgical planning of implant treatment [13].…”

“…Today, there are three practical methods for applying this technique in a clinical setting: guided surgery by using drill guides which are processed by stereolithographic rapid prototyping [15][16][17], computer-milled templates [19][20][21], and/or computer navigation systems [22]. Computer-milled templates are fabricated by drilling the final position of the implants in the scanning template itself, by using a drilling machine.…”

“…These include low temperature steam and formaldehyde at 80ºC. The template itself has been fabricated from stereocol resin (Zeneca Specialties, Blackley, Manchester, UK), which is a photo-polymerised resin and it has been FDA-approved to accurately guide the osteotomy drills [6,[16][17].…”

“…The configuration of the sleeves, as they relate to the drill, is such that there is only one direction for axial movement. Once the implants are placed, conventional protocol is followed, based on the implant system which is being used [2,6,[15][16][17].…”

Implant placement has become a routine modality of dental care.Improvements in surgical reconstructive methods as well as increased prosthetic demands,require a highly accurate diagnosis, planning and placement. Recently,computer-aided design and manufacturing have made it possible to use data from computerised tomography to not only plan implant rehabilitation,but also transfer this information to the surgery.A review on one of this technique called Stereolithography is presented in this article.It permits graphic and complex 3D implant placement and fabrication of stereolithographic surgical templates. Also offers many significant benefits over traditional procedures.
