Case Reports
A case report of tracheal tenting to the skin: An option to tracheostomy for post-thyroidectomy tracheomalacia.
Operating on a huge and long-standing goiter is challenging to the surgeon and anesthetist because of the possibility of tracheomalacia and collapse of the tracheal rings after extubation. We report our innovation of tenting the trachea to the skin using sutures (passed through the strap and sternocleidomastoid muscles) to prevent post-thyroidectomy tracheomalacia.

Gastric acid, which is among erosive substances, gradually rises to the mouth in individuals with reflux and bulimia nervosa disorders, and this causes various effects on dental restorations. ⋯ According to the data obtained, it was concluded that exposure to gastric acid affects the hardness and flexural strength properties of dental restorative ceramic materials.

E-max is a more aesthetic material than traditional zirconia. In addition, the bond strength of traditional zirconia with adhesive cements is lower. There are not enough studies on how the aesthetic values and bond strength of 5-YZP, the new generation zirconia, compare to e-max and traditional zirconia. Can 5-YZP be an alternative to e-max in terms of aesthetics and bond strength? ⋯ 5Y-PZ has a TP intermediate to those of 3Y-TZP and lithium disilicate. Long-term bond strength of 3Y-TZP and 5Y-ZP were similar to those of lithium disilicate. To be an alternative to glass ceramics in the anterior region, translucency and bond strength values need to be improved.

Case Reports
Does ligamentotaxis reduce the risk of avascular necrosis of the talus after lateral subtalar dislocation.
Lateral subtalar dislocations are rare and severe injuries caused by high-energy trauma, and they require urgent treatment. We reported two cases of lateral subtalar dislocation, which were treated with different methods. ⋯ The final outcome was poor, with avascular necrosis of the talus. Our opinion is that ligamentotaxis of the ankle and subtalar joint with unilateral external fixation unloads the talus and reduces the possibility of the development of avascular necrosis of the talus.

Implant-supported overdentures are well-known and widely accepted treatment modality to increase retention which is a crucial factor for determining patient satisfaction. The placement of two implants in the anterior region can be selected as a first-line treatment in patients with the atrophic mandibular ridge. ⋯ The results showed that the insertion of different diameters of CFR-PEEK implants led to low and homogenous stress distribution all around the implant-bone interface and stresses transferred directly to the condylar neck areas. Therefore, it was observed that CRF-PEEK implants did not change the basic behavior of the mandibula in response to frontal stresses.
