Subjects and Methods : A total of 120 specimens were made and divided into four groups, (n=30) for each group. Group A, control group made of conventional heat cured PMMA with no reinforcement. Specimens of the other groups were reinforced by the rubber modified MMT composite with different percentages (2%, 4% and 8%) by weight. Group B (2% composite), group C (4% composite) and group D (8% composite). All specimens were evaluated as regard impact strength, transverse strength, water sorption, hardness, and roughness. Results: The results of this study revealed that, impact strength values of acrylic resin denture base were increase after the addition of rubber MMT –composite at any ratio. After addition of 2% rubber MMT-composite the flexure strength was nearly similar to that of control group. While, a significant reduction occurred after adding 4% and 8% composites. Water sorption was significantly increased by the addition of 4% and 8% of rubber –MMT composite ( P < 0.05). There was a significant decrease in the micro hardness after the addition of 4% and 8 % composite, while insignificant decrease occurred with 2% ratio. As regards to surface roughness there was significant increase in the surface roughness values after addition of rubber –MMT composite for all ratios (P < 0.05). Conclusion : The most favorable properties were observed by the addition of 2% rubber –MMT acrylic composite to the heat-cured acrylic resin . However, PMMA denture base material has drawbacks such as insufficient surface hardness, low flexure and impact strength.

This prospective study was designed to evaluate three-dimensional (3-D) alveolar ridge augmentation through two stages surgical approach, using vertical alveolar distraction osteogenesis (VADO) followed by onlay sticky bone covered by collagen membrane, for augmentation of the atrophic alveolar ridge to facilitate implant installation. Subjects and Methods: Ten patients with atrophic alveolar ridge were treated by VADO. After bone consolidation the distractors were removed, implants were inserted, sticky bone graft was packed at buccal aspect, and covered by guided tissue regeneration (GTR) membrane. The implants were loaded after three months of its placement. Clinical evaluation was done to assess wound healing and implant stability. Also, the following parameters were evaluated on orthopantomography and cone–beam computed tomography; relapse in the distracted bone, crestal bone loss around the implant and bone density around the implant. All data was statistical analysed. Results: Mean vertical bone gain was 6.5 mm (range 5-8 mm), and the mean width gain was 4 mm ( range 3-5mm). There was 100% survival rate of all implants. There was significant decrease in the mean bone height throughout all periods. Also, significant improvement in bone density around the implant was reported along follow up periods.
