Effect of irrigation protocols on bone temperature control during guided implan...
Alves,Theo Gualdi; Barcellos,Leonardo Hoffmann de; Bittencourt,Hélio Radke; Oliveira,Rogerio Belle de; Teixeira,Eduardo RolimAbstract Objectives: This experimental laboratory study aimed to compare the effect of four external irrigation protocols on bone tissue heating during guided implant drilling. Methods: Forty perforations were made in ten bovine rib specimens using customized surgical templates. Four experimental groups (n=10/group) were tested: Control group = 10-ml syringe with 25°C saline solution, Group 1 = 10-ml syringe wi...
Effect of number of implants, distal implant inclination, and angled abutment o...
Geremia,Tomás; Barcellos,Leonardo Hoffmann de; Corso,Leandro Luis; Villarinho,Eduardo Aydos; Shinkai,Rosemary Sadami AraiAbstract Objectives: This nonlinear three-dimensional finite element analysis (FEA) study evaluated the effect of the number of implants, distal implant inclination, and use of angled abutments on stress magnitude and distribution in cortical bone (CB), abutment screw (AS), and prosthetic screw (PS) of implant-supported fixed complete dentures. Methods: Nonlinear 3D FEA models of mandibular fixed complete dentu...
Quality of life and mastication in denture wearers and cleft lip and palate adults
Palmeiro,Marina Rechden Lobato; Bronstrup,Mariana Bauer; Durham,Justin; Walls,Angus; Shinkai,Rosemary Sadami AraiAbstract The impact of oral rehabilitation on masticatory function and oral health-related quality of life (OHRQoL) may vary with the experience of the individual with tissue loss. Our hypothesis is that patient-centered outcomes vary among adults who have experienced large defects in the maxilla due to congenital or acquired conditions even after oral rehabilitation to restore aesthetics and function. This stu...
Development of an experimental optoelectronic device to study the amplitude of ...
Missaka,Reinaldo; Adachi,Lena Katekawa; Tamaki,Regina; Shinkai,Rosemary Sadami Arai; Campos,Tomie Nakakuki de; Horikawa,OswaldoThis study aimed to present a wireless mandibular motion tracking device and optoelectronic data acquisition system developed to analyze the real-time spatial motion of the entire mandible during mouth opening and closing with no restriction of any movement. The procedures were divided into three phases: confection of a kinematic arch, dynamic digital video image acquisition, and image processing and analysis b...
Effect of microwave disinfection on denture base adaptation and resin surface r...
Sartori,Evandro Afonso; Schmidt,Caroline Bom; Walber,Luiz Fernando; Shinkai,Rosemary Sadami AraiThis study evaluated the effect of disinfection methods [chemical disinfection (immersion in 100 ppm chloride solution) or microwave disinfection (690 W for 6 min)] on the internal adaptation of denture bases and resin surface roughness. For the adaptation test, 18 maxillary denture bases were obtained from stone casts duplicated from a metallic master model and submitted to the following treatments: 1) control...
Functional evaluation of oral rehabilitation with removable partial dentures af...
Cosme,Dúcia Caldas; Baldisserotto,Simone Michielon; Fernandes,Eduardo de Lima; Rivaldo,Elken Gomes; Rosing,Cassiano KuchenbeckerMost removable partial denture (RPD) wearers are satisfied with their prostheses, but the factors that influence satisfaction and acceptance are still not determined. OBJECTIVE: This study explored technical, biological, and satisfaction variables for the functioning of RPDs after five years, and compared the evaluation by the patient and by the clinician. MATERIAL AND METHODS: Fifty adults (39 females, 11 male...
Adaptation of complete denture bases submitted to chemical polishing
Gomes,Márcia; Broilo,Josué Ricardo; Walber,Luiz Fernando; Maccari,Paulo César Armani; Shinkai,Rosemary Sadami AraiOBJECTIVE: This study evaluated the effect of chemical polishing on the internal adaptation of complete denture bases fabricated with Veracril® resin and polymerized by either the conventional (C) or microwave (M) techniques. MATERIAL AND METHODS: Six groups (n=6/group) were tested: 1) C + no polishing (CO); 2) C + chemical polishing (CQ); 3) C + immersion in hot water at 75ºC (CW); 4) M + no polishing (MO); 5)...
Reliability of a digital image method for measuring medial mandibular flexure i...
Shinkai,Rosemary Sadami Arai; Canabarro,Simone de Andrade; Schmidt,Caroline Bom; Sartori,Evandro AfonsoMedial mandibular flexure (MMF) is the functional approximation of hemi-mandibles in jaw opening and protrusion, which may affect conventional or implant-supported arch prostheses. OBJECTIVE: This study evaluated the intra- and inter-rater reliability of a digital image method for linear measurement of MMF in dentate subjects. MATERIAL AND METHODS: Mandibular occlusal impressions in vinyl polysiloxane during re...
O papel da odontologia na equipe interdisciplinar: contribuindo para a atenção ...
Shinkai,Rosemary Sadami Arai; Del Bel Cury,Altair AntoninhaEste trabalho bibliográfico teve por objetivo discutir a atuação da odontologia na atenção integral à saúde do idoso, considerando-se a necessidade da abordagem interdisciplinar. É apresentada a atual situação da odontologia geriátrica e os problemas que ocorrem no Brasil pela falta de estudos específicos e de recursos humanos capacitados em geriatria e gerontologia dentro da odontologia. São destacadas as inte...
