Aim: To evaluate retention of complete denture base with different types of posterior palatal seals.
Material And Methods: Ten male patients between the age group of 50 years to 60 years were selected for the study. After the primary and secondary impressions were taken, five casts were made including a cast without posterior palatal seal, a cast with single bead posterior palatal seal, a cast with double bead posterior palatal seal, a cast with butterfly shaped posterior palatal seal, and a cast with posterior palatal seal with low fusing compound by functional method.
Results: It was observed that retention increased up to 108% in the posterior palatal seal with low fusing compound with functional method and the posterior palatal seal that was obtained by using functional method provided greater retention than a denture base without posterior palatal seal.
Conclusion: It was concluded that the incorporation of a posterior palatal seal is important for obtaining optimum retention of the maxillary complete denture.

This study aimed to compare the dimensional alterations of the dental arches and the palate symmetry in patients with unilateral complete cleft lip and palate before and after the performance of primary surgeries by different surgical techniques. The sample was divided into Group 1, G1 - cheiloplasty (Millard technique) and single-stage palatoplasty (von Langenbeck technique); Group 2, G2 - cheiloplasty (Millard technique) and two-stage palatoplasty (Hans Pichler and Sommerlad techniques). The digital dental models were evaluated before (Time 1, T1) and after (Time 2, T2) primary surgeries.

Aim: In this study, it was aimed to determine the changes in the anatomic structures of individuals with obstructive sleep apnea syndrome (OSAS) classified according to the apnea-hypopnea index (AHI).
Materials And Methods: Individuals were divided into groups as group 1 (AHI=0, n=20), group 2 (AHI ˂5, n=20), group 3 (AHI=5-15, n=20), group 4 (AHI=16-30, n=20), group 5 (AHI ˃30, n=20). The individuals left lateral cervical vertebra radiographs were taken.

Objective: This study aimed to evaluate the skeletal, dental, and soft tissue effects of the nickel titanium memory Leaf Expander in a growing sample of patients with unilateral posterior crossbite compared with a control group using digital models and lateral cephalometric radiographs.
Methods: The research included a total of 24 patients, 12 of whom were treated and 12 untreated. The Leaf Expander group consisted of 4 males and 8 females (mean age= 8.

Background: The present study aims to evaluate a three-dimensional (3D) changes in the crestal bone levels (buccally, lingually/palatally, mesially, and distally) and in the thickness of keratinized tissue around single or multiple implants using cone-beam computed tomography (CBCT) after 1 year.
Materials And Methods: Twenty-eight implants were placed in the posterior load-bearing areas in 10 patients. The crestal bone levels and the thickness of keratinized tissue surrounding the edentulous area were assessed preoperatively, immediately after implant placement, and 1 year after implant placement using CBCT (3D imaging technique with DICOM software (Carestream Health, Rochester, NY)).
Estimating Palatal and Pharyngeal Muscle Contraction in Hindi Syllable Pronunciation using Computational Modeling.

Speech, one of the main functions affected by cleft palate, involves a complex orchestra of sound deformation by various organs including the larynx, pharynx, epiglottis, palate, tongue, lip, and other structures complementing them. Although the effects of palatoplasty are traditionally evaluated subjectively, objective parameters have seldom been described to compare the pre- and postrepair functions. The study tries to extract the palatal and pharyngeal muscles while uttering various Hindi syllables and tries to find the percentage contraction of these structures as an objective assessment.
