Case report Two cases, one of an adoescent female patient and the other of an adult female, are presented, describing step-by-step the clinical and laboratory procedures. The controls after 6 months are also reported. Conclusion Further randomized clinical trials are required in order to evaluate durability and efficacy and periodontal parameters in patients treated with this new type of retainer.</p> T. Doldo L.

FIPS was applied for objective outcome assessment beside clinical and radiographic examinations. Five variables were defined for evaluation, resulting in a maximum score of 10 per implant restoration. The patients’ level of satisfaction was recorded and correlated with FIPS. <strong>Results</strong> All implants and connected crowns revealed survival rates of 100% without any biological or technical complications after three years of loading. The total FIPS recorded for group 1 was 44, 43 in group 2 and 42 in group 3. The mean total FIPS score was 8.6±1.1, ranging from 6 to 10. The variable “bone” revealed the highest scores (2.0; range: 2–2), as well “occlusion” (2.0; range: 2–2). Mean scores for “design” (1.7 ±0.4; range: 1–2), “mucosa” (1.6±0.5; range: 1–2), and “interproximal” (1.5±0.6; range: 1–2) were more challenging to satisfy. The patients expressed a high level of functional satisfaction (80.5±2.5; range: 65–100). No type of connection showed to be superior to the other two. No statistically significant differences were found among the three tested groups. A significant correlation was found between FIPS and the subjective patients’ perception with a coefficient of 0.80 (P &lt; 0.0001). <strong>Conclusions</strong> The findings of the clinical trial indicated the great potential of both conical and hexagon connections and their good performance after 1 year of clinical service. FIPS showed to be an objective and reliable instrument to assess implant success.</p> E. Ferrari Cagidiaco F. Carboncini S. Parrini T. Doldo M. Nagni N. Uti M.

Case report A 55 years old patient came to the outpatient clinic of the prosthodontics department, Faculty of Oral and Dental Medicine, Cairo University seeking for complete denture prosthesis to restore function and esthetics. He reported problems with his complete dentures as he had an exaggerated gagging reflex which interfered with upper denture wearing. Besides, his mandibular denture was unstable and poorly fitted. This patient was strongly recommended for implant prosthesis and, because of his low financial conditions, an implant overdenture was the most proper treatment. Four implants were placed in the upper arch with self-aligning attachment and two implants in the lower arch with self-aligning attachments. Conclusion Implant overdenture is a simple, easy, comfortable, effective solution for restoring edentulous patients at a low cost and&nbsp;with no need for bone augmentation procedures.</p> A. Z.

This study was done to assess radiographically the quantity and quality of bone formed in the region of mandibular first molar after extraction of the tooth and immediate implant placement with Concentrated Growth Factor (CGF) grafting. <strong>Materials and methods</strong> A total of 10 subjects were selected for this prospective study. Extraction of mandibular first molars was carried out and implants were immediately placed with CGF grafting. A Cone Beam Computed Tomography (CBCT) was taken immediately after implant placement and after six months of undisturbed healing, radiographic evaluation was carried out using CBCT to assess the quantity and quality of new bone formed around implants. The collected data were statistically analyzed. <strong>Results</strong> CBCT results showed a mean bone gain of 2.3 mm in buccal, 1.52 mm in lingual, 2.97 mm in mesial and 4.26 mm in distal aspect respectively. No statistically significant change was noticed in bone density comparing the first two and last two threads of implants inserted with concomitant placement of CGF into the extraction socket. <strong>Conclusion</strong> This study indicates the possibility to perform immediate implant placement in fresh extraction sockets with the use of CGF as an alternative to conventional grafting. Further research needs to be carried out on the subject to validate the results obtained in this study.</p> S. Manoj J. Punit H. Chethan J.
