Objective: To investigate the clinical immediate load at an angle after immediate placement of the implant.
Methods: Select 4 adult dogs; through establishing the angle loading animal experiment model, perform lateral loading on 32 implants respectively at vertical and 0°, 10°, and 20°, with which as a basis for grouping, determine the osseointegration index and new bone growth rate; and observe the peri-implant bone remodeling conditions.
Results: The 20° group is found with the most obvious bone absorption, and compared with other groups, its osseointegration index and new bone growth rate are statistically significant (P < 0.
This study was designed to investigate the effects of local delivery of adipose-derived stem cells (ADSCs) transfected with transcription factor osterix (OSX) on bone formation during distraction osteogenesis. New Zealand white rabbits (n=54) were randomly divided into three groups (18 rabbits per group). A directed cloning technique was used for the construction of recombinant plasmid pEGFP-OSX, where EGFP is the enhanced green fluorescence protein.

This study was designed to investigate the effects of local delivery of bone marrow mesenchymal stem cells (BMMSCs) with or without osterix (OSX) gene transfected on bone regeneration in the distracted zone using a rabbit model of mandibular lengthening. Fifty-four New Zealand white rabbits underwent osteodistraction of the left mandible and were then randomly divided into group A, group B, and group C (n = 18 for each group). At the end of distraction BMMSCs transfected with OSX, autologous BMMSCs and physiological saline were injected into the distraction gaps in groups A, B, and C, respectively.

A high-flow maxillary arteriovenous malformation fed by multiple arteries, including bilateral internal maxillary arteries and ophthalmic artery, is reported. A combination of polyvinyl alcohol particles and N-butyl-cyanoacrylate mixed with lipiodol was progressively deposited within the distal vascular bed by transarterial superselective embolization of the branches of bilateral internal maxillary arteries, resulting in complete anatomic and clinical cure. The authors feel that this approach is more secure and effective compared with transfemoral venous embolization and direct transosseous puncture.

Methods: The total 384 implants of different materials and shapes were inserted normally. According to the Chinese standard of dental implantation, the success rates of three types were compared.
