rehabilitation of a dentate mandible requiring a full arch rehabilitation immediate loading of a fixed complete denture on 8 implants placed with a bone supported surgical computer planned guide a case report
Journal of Oral Implantology, 2011Co-Authors: Leonardo Amorfini, Stefano Storelli, Eugenio RomeoAbstract:The use of technologies that merge computerized tomography X-ray imaging and 3-dimensional (3D) planning software allow the surgeon to digitally elaborate on the computer the position, length, and diameter of every implant to be placed. Following this approach, the placement is guided in a 3D digital model, and the implants are placed in the final position avoiding eventual anatomic structures. In this case report, the patient's remaining mandibular teeth were extracted, and the patient received 8 implants with the help of a computer surgical guide. The case was planned using SimPlant and a bone-supported guide. Because of the high precision of the planning, it was possible to realize a provisional rehabilitation before the actual surgery. The planning allows placement of parallel implants to optimize the Prosthetic Procedure and outcome. An immediate provisional implant was fixed with a flow composite on the temporary abutments and then refined in the dental laboratory. The patient received the provision...

implant retained mandibular overdentures with iti implants
Clinical Oral Implants Research, 2002Co-Authors: Eugenio Romeo, M Chiapasco, Andrea Lazza, P Casentini, Marco Ghisolfi, Marco Iorio, G VogelAbstract:Abstract: This prospective study has been designed to compare the results of immediate and delayed loading of implant-retained mandibular overdentures after a 2-year follow-up. Twenty patients have been randomly divided into two groups. Group 1 patients (test group) received four ITI implants in the intraforaminal area of the mandible. Octa® abutments were immediately screwed on implants; 2 days after surgery, the implants were rigidly connected with a U-shaped Dolder gold bar and loaded with an overdenture. Group 2 patients (control group) received, in the same area, the same type and number of implants, which were left to heal according to the standard protocol. At 3–4 months, Octa abutments were screwed on the implants and the same Prosthetic Procedure of the test group was applied. The minimum follow-up period lasted 2 years, with recall appointments at 2 weeks, 1, 3, 6 months, 1 year and every following year postoperatively, evaluating: MPI, MBI, PD, Periotest® and radiographic peri-implant bone resorption. Success criteria according to Albrektsson et al. were used. Only one implant out of the 40 of group 2 failed, whereas none failed in group 1. No statistical difference of the clinical parameters evaluated was noticed in the two groups. Therefore, immediate loading of implants, if connected with a U-shaped bar, can provide the same results of the ‘traditional’ technique as far as osseointegration and short-term survival rates of implants are concerned. Moreover, this method significantly shortens the treatment period, thus increasing patient satisfaction.

implant retained mandibular overdentures with branemark system mkii implants a prospective comparative study between delayed and immediate loading
International Journal of Oral & Maxillofacial Implants, 2001Co-Authors: M Chiapasco, Eugenio Romeo, S Abati, G VogelAbstract:This study was designed to compare the results of immediate and delayed loading of implants with implant-retained mandibular overdentures. Ten patients (test group) received 40 Branemark System MKII implants (4 per patient) placed in the interforaminal area of the mandible. Standard abutments were immediately screwed to the implants, rigidly connected with a bar, and immediately loaded with an overdenture. Ten patients (control group) received the same type and number of implants in the same area, but the implants were left to heal submerged. Four to 8 months later, standard abutments were screwed to the implants and the same Prosthetic Procedure was applied. Each implant was evaluated at the time of Prosthetic loading and at 6, 12, and 24 months after the initial Prosthetic load with the following parameters: modified Plaque Index (MPI), modified Bleeding Index (MBI), probing depth (PD), and Periotest. Peri-implant bone resorption was evaluated on panoramic radiographs taken 12 and 24 months after initial Prosthetic loading. No significant differences were found between the 2 groups regarding MPI, MBI, Periotest, peri-implant bone resorption, and PD at 6 and 24 months (P > .05). The only difference was found regarding PD values on the mesial and lingual sites at 12 months (P < .05). The cumulative success rate of implants was 97.5% in both groups. Results from this study showed that immediate loading of endosseous implants rigidly connected with a U-shaped bar does not seem to have any detrimental effect on osseointegration. Conversely, this method significantly shortens the duration of treatment with relevant satisfaction for the patients. ( INT J ORAL MAXILLOFAC IMPLANTS 2001;16:537‐546)

minimally invasive digital implant Prosthetic Procedure in all on 4 rehabilitation in patients with special needs a three year follow up
Journal of Biological Regulators and Homeostatic Agents, 2021Co-Authors: A Merlone, M Manacorda, G Tete, N Cantile, F CattoniAbstract:The present study describes an innovative Procedure for resolving implant-Prosthetic cases in patients with edentulous special needs. In 2017 a 56-year-old female patient came to the Department of Dentistry of Vita-Salute San Raffaele Hospital, Milan, Italy, requiring implant-Prosthetic rehabilitation of the dental arches given the difficulty in wearing removable prostheses. The first level radiological examinations were evaluated, two technical photographs were taken with specific reference, the 2D Digital Smile Design (Smile Design) was then carried out, the provisional prosthesis was performed and the CBCT requested with repere and provisional prostheses to realize the computerized implant project and an atraumatic flapless guided surgery. Professional oral hygiene sessions were performed quarterly, and the 3-year follow-up revealed no complications affecting the Prosthetic or implant component. We can therefore conclude that the proposed method, exploiting digital technologies and flows and minimally invasive flapless surgical methods, can be considered elective in the treatment of patients with special needs.

a 3 d cad cam technique in full arch implant supported rehabilitations the virtual implant Prosthetic Procedure vipp technique a prospective longitudinal study
Journal of Osseointegration, 2018Co-Authors: Giorgio Gastaldi, Enrico Gherlone, M Manacorda, Francesco Ferrini, F Bova, Raffaele Vinci, F CattoniAbstract:ABSTRACT Aim The purpose of this study is to evaluate the success of a new three-dimensional CAD/CAM processing technique in full-arch implant supported rehabilitations of edentulous patients. Materials and methods Healthy patients with edentulous mandible and/or maxilla arch were selected for the present study. The Full-Arch Implant Supported Virtual Protocol has been applied with immediate loading fixed rehabilitation. Effectiveness of digital and surgical planning, marginal bone loss, implant and Prosthetic failure were recorded at 6-and 12 months follow up. Results Seventy-six implants were placed in 15 patients, and 15 full arch rehabilitations were delivered. Patients found smile design previsualization very effective (93%), guided surgery very effective (94%), and immediate loading and temporization very effective (92%). No implant were lost (survival rate = 100%). At the 6-months radiographic evaluation, average perimplant crestal bone loss was 0.56 ± 0.12 mm for maxillary implants (n = 64 ), 0.59 ± 0.16 for mandibular implants (n = 12 ) and 12-months average perimplant crestal bone loss was 0.67 ± 0.11 mm for maxillary implants (n = 64 ) and 0.69 ± 0.16 for mandibular implants (n = 12 ). Two unscrewing episodes and one provisional prosthesis fracture occurred. No paresthesia and no Prosthetic complications in definitive prostheses were registered in the whole sample. Conclusions Within the limitations of the present study, the Virtual Implant-Prosthetic Procedure could be a satisfactory treatment in edentulous patients.
