Filter by:To compare the effect of two control intervals (once every 4th week or once every 6th week) on the wear time of a Twin Block removable appliance.
The aim of this study is to assess if there are significant differences in the failure rate of stainless steel and ceramic brackets. For this study, patients will be enrolled and divided into two groups, according to the type of brackets (stainless steel or ceramic) used for orthodontic treatment. Failure rates will be recorded every month for 12 months and survival analysis will be performed, together with skeletal and space analysis.
The aim of this study is to assess if there are significant differences in periodontal conditions between patients undergoing fixed orthodontic treatment with stainless steel or ceramic brackets. For this study, patients will be enrolled and divided into two groups, according to the type of brackets (stainless steel or ceramic) used for orthodontic treatment. A professional supragingival and subgingival oral hygiene will be performed before the bonding of the orthodontic brackets together with a periodontal evaluation will be recording the following periodontal indices: PPD, BoP, BS, GI, PI, BEWE and Schiff Air Index. Indices will be recorded after 1, 3 and 6 months after the bonding, separately for both in maxillary and in mandibular dental arches and only for teeth with brackets bonded.
The aim of this study was to evaluate the changes in head posture, position of the hyoid bone, pharyngeal airway and cervical posture after the use of Petit type face mask in patients with skeletal class III malocclusion (ANB angle < 0) with ongoing growth. No other study was found in the literature in which head posture, cervical posture, and hyoid bone position were evaluated after the use of a face mask and compared with a control group consisting of patients of the same age group and the same malocclusion.
To analyze the distalization or distal tooth displacement and derotation angle produced by Carriere Motion Appliance® (CMA) by using a repeatable and reproducible measurement digital technique.
The aim of the present project is to analyze the impact from orthognathic surgery on the upper airway respiratory volume. The primary objective is comparison of differences in the in the airway changes due to maxillary movements and mandibular movements. Secondary objectives are the analysis of any correlation between the magnitude of the movement and the airway volume, correlation between the direction of the movements and the changes in airway volume and correlation with Health-Related Quality of Life (HRQoL). Expected confounding factors like smoking habits and Body Mass Index (BMI) will be analyzed.
This study aims to estimate the levels of pain and discomfort associated with the en-masse retraction of the six upper anterior teeth and assisted by either conventional or flapless corticotomy. Thirty-four adult patients exhibiting class П division 1 malocclusion will be randomly allocated to either the conventional corticotomy group or the flapless corticotomy group, and they will be treated by extraction of maxillary first premolars with applying mini-screws between maxillary second premolar and first molar as temporary skeletal anchorage devices (TSADs). The levels of pain and discomfort will be rated after 24 hours of corticotomy (T1), four days (T2), seven days (T3), 14 days (T4) and after 28 days of corticotomy, by asking the patients to fill in a questionnaire for assessing levels of pain and discomfort.
Malocclusions in adolescents may affect oral health related quality of life. The study aims at; 1. Evaluating two instruments measuring oral health related quality of life; "Child Perceptions Questionnaire 11-14" (CPQ 11-14) short form and "Psychosocial Impact of Dental Aesthetics Questionnaire" (PIDAQ). 2. Comparing differences in oral health related quality of life in; 1. adolescents with different types of malocclusion and without malocclusions 2. individuals of different genders and socioeconomic status 3. Longitudinally evaluating differences in oral health related quality of life; 1. before, during and after orthodontic treatment 2. in untreated individuals (without malocclusion) over time
Patients who have moderate crowding will be treated in this study. The efficacy of showing the predicted alignment of patient's teeth at the end of orthodontic treatment previously to treatment on their expectations from orthodontic treatment and their satisfaction with their teeth alignment will be assessed.
Corticotomy and micro-osteoperforation (MOP) have been proven to accelerate tooth movement and shorten orthodontic treatment time, compared to conventional treatment. MOP is less invasive; however, it is unclear whether it is as effective as a corticotomy. The purpose of this study was to compare the maxillary canine retraction achieved by these techniques.
