Safe regions of miniscrew implantation for distalization of mandibular dentition with CBCT Prog. Orthod. (IF 1.822) Pub Date : 2019-12-09 Haibo Liu; Xiaoxue Wu; Jun Tan; Xiao Li
To assess the anatomy of the mandibular buccal shelf (MBS) with cone-beam computed tomography (CBCT) and to identify the region of miniscrew implantation for the distalization of mandibular dentition. The MBS was assessed in 80 patients at four regions as follows: (i) between the buccal root of the mandibular second premolar and the mesiobuccal root of the first molar (L5b–L6mb), (ii) between the mesiodistal

Effects of different nose types on class II treatments for female patients. Prog. Orthod. (IF 1.822) Pub Date : 2019-12-02 Ozkan Semih Cankaya,Fatih Celebi,Ali Altug Bicakci
The aim of this study was to evaluate the effect of different nose types on the perception of facial aesthetics following camouflage treatment and orthognathic surgery for skeletal class II female patients. A pre-treatment profile photograph of a skeletal class II adult patient was selected from the department archive. Two constructed photographs were created to represent orthognathic surgery and camouflage

Facial esthetic outcome of functional followed by fixed orthodontic treatment of class II division 1 patients. Prog. Orthod. (IF 1.822) Pub Date : 2019-11-25 Mary-Eleni Zouloumi,Kleopatra Tsiouli,Simeon Psomiadis,Olga-Elpis Kolokitha,Nikolaos Topouzelis,Nikolaos Gkantidis
To assess the perceived facial changes in class II division 1, convex profile patients treated with functional followed by fixed orthodontic appliances. The study sample consisted of 36 pairs of pre- and post-treatment photographs (frontal and profile, at rest) of 12 patients treated with activator, 12 with twin-block, and 12 controls with normal profiles, treated without functional appliances.

Estimation of root inclination of anterior teeth from virtual study models: accuracy of a commercial software. Prog. Orthod. (IF 1.822) Pub Date : 2019-11-22 Panagiota Magkavali-Trikka,Demetrios J Halazonetis,Athanasios E Athanasiou
The aim of the study was to assess the accuracy of commercially available software in estimating anterior tooth root inclination from digital impressions of the crowns of the teeth. Following sample size calculation and application of inclusion and exclusion criteria, 55 anterior natural teeth derived from 14 dry human skulls were selected. Impressions were taken and plaster study models were fabricated

Usage and comparison of artificial intelligence algorithms for determination of growth and development by cervical vertebrae stages in orthodontics. Prog. Orthod. (IF 1.822) Pub Date : 2019-11-15 Hatice Kök,Ayse Merve Acilar,Mehmet Said İzgi
Growth and development can be determined by cervical vertebrae stages that were defined on the cephalometric radiograph. Artificial intelligence has the ability to perform a variety of activities, such as prediction-classification in many areas of life, by using different algorithms, In this study, we aimed to determine cervical vertebrae stages (CVS) for growth and development periods by the frequently

3D evaluation of maxillary morphology in Marfan growing subjects: a controlled clinical study. Prog. Orthod. (IF 1.822) Pub Date : 2019-03-19 Giuseppina Laganà,Daniel Palmacci,Giovanni Ruvolo,Paola Cozza,Valeria Paoloni
BACKGROUND Marfan syndrome is a rare autosomal dominant inherited disease of the connective tissue associated with various craniofacial abnormalities. Aim of the present study was to assess the variability of palatal shape in a sample of 31 Marfan patients compared to a control group of no syndromic subjects, in two stages of dentition, by using 3D geometric morphometric analysis. METHODS Thirty one

Clear aligner treatment: different perspectives between orthodontists and general dentists. Prog. Orthod. (IF 1.822) Pub Date : 2019-03-12 Fabrizia d'Apuzzo,Letizia Perillo,Caroline K Carrico,Tommaso Castroflorio,Vincenzo Grassia,Steven J Lindauer,Bhavna Shroff
PURPOSE To evaluate differences between orthodontists and general dentists in experience with clear aligners (CA), patients' demand and perception, types of patients, and malocclusion treated with CA and to compare the two groups of clinicians not using CA in their practice. METHODS A Web-based survey was developed and sent to the 129 members of the European Aligner Society and randomly to 200 doctors

Maxillary posterior intrusion with corticotomy-assisted approaches with zygomatic anchorage-a finite element stress analysis. Prog. Orthod. (IF 1.822) Pub Date : 2019-03-05 Cemile Uysal,Burcu Baloş Tuncer,Cumhur Tuncer
BACKGROUND Anterior open bite is one of the most difficult malocclusions to treat and maintain in orthodontics. An effective treatment approach to correct anterior open bite is the intrusion of maxillary posterior teeth. The aim of this study was to evaluate the effects of corticotomy-assisted posterior maxillary intrusion with zygomatic anchorage by using finite element stress analysis. METHODS An

Are there benefits from using bone-borne maxillary expansion instead of tooth-borne maxillary expansion? A systematic review with meta-analysis. Prog. Orthod. (IF 1.822) Pub Date : 2019-02-26 Marietta Krüsi,Theodore Eliades,Spyridon N Papageorgiou
BACKGROUND The aim of the current systematic review was to compare the clinical effects of bone-borne or hybrid tooth-bone-borne rapid maxillary expansion (RME) with conventional tooth-borne RME in the treatment of maxillary deficiency. METHODS Nine databases were searched up to September 2018 for randomized clinical trials comparing bone-borne or hybrid tooth-bone-borne RME to conventional tooth-borne
