The authors present a new design of splintage for fixation of the alveolar ridge mucosa following various vestibuloplasty procedures. From 1981-1987 50 acrylic buccal splints and 76 palatal splints were used, fixed by AO screws, in vestibuloplasty procedures. By using screws a controlled pressure equally distributed over the mucosa was achieved. The results demonstrate that screw fixation of the splints can avoid some of the common problems found especially with suture or nails. The acrylic buccal splint fixed by AO screws on to the alveolar bone is more convenient for the patient and produces a better operative result. The authors recommend it as the method of choice for submucosal and some modified submucosal vestibuloplasties.

The posterior mandible is the primary area for occlusal function. However, long-term tooth loss in the posterior mandible often leads to rapid absorption of both buccal and lingual trabecular bone plates and subsequent atrophy of the alveolar ridge. This ultimately results in horizontal bone deficiencies that complicate achieving an optimal three-dimensional placement for dental implants.

Introduction: The primary objective of any implant system is to achieve firm fixation to the bone, which can be influenced by both biomechanical factors and biomaterial selection. An array of materials is used for the replacement of missing teeth through implantation. The appropriate selection of biomaterials directly influences the clinical success and longevity of implants.

This study introduced a novel dual fixation method for the pulmonary vasculature and lung tissue in pulmonary hypertension (PH) rats, addressing the limitations of traditional fixation methods that failed to accurately preserve the in vivo status of pulmonary vascular morphology. The modified method involved a dual fixation process, combining individualized ventilation support and vascular perfusion to simulate the respiratory motion, pulmonary artery pressure and right ventricular output of the rat under in vivo conditions. Utilizing a monocrotaline-induced PH rat model, this study compared the dual fixation with the traditional immersion fixation, focusing on the quantitative assessment of alveolar expansion degree, capillary patency, endothelial cell quantity and wall thickness of pulmonary vein and artery.

Introduction And Aims: Implantation of the posterior maxilla with insufficient bone height faces challenges. Studies have shown that the use of ultrashort implants can avoid additional damage. This finite element analysis study aimed to evaluate the impacts of different lengths of ultrashort implants and three surgical approaches on stress, strain, and displacement in the posterior maxilla with varying bone heights.

A total of 384 animals (sheep, goat, cattle, and buffalo) were examined for the presence of hydatid cysts only in the lungs. The lung tissue samples associated with the hydatid cyst were collected immediately after slaughter, followed by fixation in 10% formalin. The fixed tissue was subjected to paraffin embedding technique.
