Objective: To evaluate the effectiveness of mini-screw anchorage on intruding upper incisors in patients with gummy smile.
Methods: Sixteen female patients (mean age: 23.8 years) were involved in this study. The mini-screws were placed between upper lateral incisors and canines on both sides for intruding upper incisors together with fixed appliance. The cephalometric analysis was carried out.
Results: Totally 63 teeth in 16 patients were intruded successfully and the deep overbite was decreased by (2.74 +/- 2.00) mm (P < 0.001). The distance from the edge of the upper incisor to palatal plane was reduced by (5.00 +/- 2.76) mm (P < 0.001), and the incisors were proclined by (9.34 +/- 10.06) degrees (P < 0.01). The duration for intrusion was 10.8 months on average.
Conclusions: It was practicable and effective to improve gummy smile by intruding upper incisors with mini-screw implant.

SOX9 encodes an SRY-related transcription factor critical for chondrogenesis and sex determination among other processes. Loss-of-function variants cause campomelic dysplasia and Pierre Robin Sequence, while both gain- and loss-of-function variants cause disorders of sex development. SOX9 has also been linked to scoliosis and cancers, but variants are undetermined.

Tooth shade selection is a fundamental factor in the success of dental restorations, and visual impairment may adversely affect this process. The aim of this cross-sectional clinical study was to determine whether visual impairment influences shade selection using two methods: spectrophotometry and shade guides. : The sample consisted of 2796 maxillary and mandibular teeth, and shade selection was measured subjectively with a shade guide (VITA Classic, VITA Zahnfabrik) and objectively with a spectrophotometer (VITA Easyshade V, VITA Zahnfabrik, Bad Säckingen, Germany).

The literature suggests that the cranial base angle is considered one of the contributing factors to sagittal jaw malpositions when its relationship with the viscerocranium is examined. Our study aims to compare and evaluate the outcomes of fixed functional orthopedic treatment in patients with mandibular retrognathia across different cranial base groups. Participants were treated at Erciyes University with fixed functional appliances and categorized by CBA into low (<130°), medium (130°-134°), and high (>134°) groups.

This case report emphasizes the complexities involved in dental implant placement within the anterior esthetic zone, focusing on the integration of advanced surgical techniques and meticulous prosthetic design for optimal esthetic and functional results. A 28-year-old male presented with the absence of the upper left central incisor, which had been extracted 5 years prior due to fracture. Clinical and radiographic assessments indicated normal alveolar bone levels; however, the esthetic demands required a specialized approach.
