During the planning of oral rehabilitation, the vertical dimension of occlusion (VDO) is one of the first parameters to be measured since its improper restoration can lead to the failure of any prosthetic rehabilitation. A decreased VDO can lead to the appearance of lesions, such as angular cheilitis, facial disharmony, and temporomandibular disorders; meanwhile, an increased VDO may lead to the onset of joint and muscle pain, tension in functional speech, difficulty in swallowing, impaired chewing, tooth sensitivity due to traumatogenic forces, pathologic bone resorption, abnormal wearing of teeth, the appearance of an elongated face, and a facial expression of fatigue. Most scientific articles deal with methods and techniques for re-establishing VDO in edentulous patients or those who have lost their tooth reference due to prosthetic preparations. However, patients with increased VDO are also found in everyday practice. One treatment option for these patients is occlusal adjustment by selective tooth wear; it is still possible to perform orthodontic intrusion and/or orthognathic surgery in severe cases. The aim of this study was to discuss signs, symptoms, diagnosis, and treatment, and to report a clinical case of a patient with increased VDO.

Background Invasive cervical resorption (ICR) is not well understood by the professional, being misdiagnosed, leading to inappropriate treatment and unnecessary loss of tooth. Introduction ICR is defined as a localized process of resorption, which begins in the cervical area of the tooth, just below the epithelial junction and above the ridge crest in the area of the connective tissue insertion. Possible predisposing factors include external trauma, orthodontic movement, surgical procedures, periodontal disease and its treatments, endogenous bleaching, pressure generated by wind instruments and herpes virus infection. Different approaches have been suggested for the treatment of ICR, depending on the extent of the lesion and its location. However, in some cases due to the severity of the injury, there is no alternative but to tooth extraction, followed by restoration of the edentulous area. Aim and objective Discuss etiology, diagnosis and classification of the ICR, as well as different treatment options. Also is presented a case in which extraction was carried out, installation of the implant and ceramic crown, subsequent to a treatment approach that resulted in failure in the short-term period. Conclusion Early diagnosis of the ICR is critical to proper treatment and favorable prognosis. Interdisciplinary treatment should be instituted as soon as possible, avoiding the loss of the affected tooth. In advanced cases, treatment involving the installation of osseointegrated implants should be considered the first choice of treatment. Clinical significance Early diagnosis of the ICR is critical do prevent unnecessary tooth loss, once the prognosis for advanced cases is doubtful.

Introdução: Dentre as modalidades terapêuticas disponíveis para reabilitar desdentados totais, a prótese total removível é a mais utilizada. No entanto, pacientes que ainda possuem dentes remanescentes, indicados para exodontia, podem se mostrar resistentes em permanecer sem seus dentes durante o período de cicatrização dos tecidos, para posterior incorporação das próteses. Outro problema observado é a falta de retenção e estabilidade normalmente apresentada pelas próteses mandibulares. A utilização de prótese total imediata maxilar e overdenture mandibular implantorretida pode solucionar esses problemas. Objetivo: O objetivo desse trabalho é apresentar um relato de caso clínico desenvolvido em um projeto de extensão da Faculdade de Odontologia da Universidade Federal de Minas Gerais, que atende pacientes com grave comprometimento dento-periodontal. Relato do caso: Paciente do sexo masculino, 49 anos, apresentou-se para tratamento com grave quadro de saúde bucal, com indicação de exodontia de todos os dentes remanescentes. Foi planejada a confecção de prótese total maxilar e overdenture mandibular implantorretida, ambas imediatas. Os procedimentos foram desenvolvidos seguindo o protocolo de atendimento preconizado no Projeto. Este protocolo contempla basicamente: (1) exodontia dos dentes posteriores com os devidos acertos ósseos; (2) moldagens; (3) registros intraorais; (4) prova dos dentes; (5) exodontia e acerto ósseo na região anterossuperior; (6) instalação da prótese maxilar; (7) exodontia dos dentes anteroinferiores; (8) acerto do rebordo ósseo; (9) instalação de implantes na região interforaminal; (10) captura da prótese total mandibular como uma overdenture, em carga imediata. Após 90 dias, foram realizados os re-embasamentos necessários. Resultados: O paciente foi acompanhado periodicamente por três anos, sempre demostrando satisfação com o tratamento recebido. Conclusão: A adoção desse protocolo mostrou-se eficaz para reabilitação de pacientes com grave comprometimento dentário.   COMPLETE DENTURE AND IMMEDIATE OVERDENTURE:  A THREE-YEAR FOLLOW-UP CASE REPORT   ABSTRACT Introduction: Among the available therapeutic modality to rehabilitate total edentulous patients, the removable complete dentures are the most used. However, patients who still have remaining teeth,  suitable for a dental extraction, might be hard to convince they should keep their teeth during the tissue healing process, and then insert the denture. Other problems observed were the lack of retention and stability commonly delivered by mandibular dentures.  The use of maxillary complete immediate denture and implant-retained mandibular overdenture may solve these problems. Purpose: this paper aims to introduce a clinical case report developed by an extension project at the Dentistry Department of the Federal University of Minas Gerais, that cares for patients with severe dental periodontal impairments. Case report: A male, 49-year-old patient, submitted himself to treatment with a major oral health state, suitable for dental extraction of all the remaining teeth. The complete maxillary denture and mandibular overdenture confection was assigned, both immediate.  The procedures were performed following the assistance protocol proposed by the Project. Such protocol basically included (1) dental extraction for posterior teeth and proper bone remodeling; (2) Dental impressions; (3) intra-oral record; (4) teeth testing; (5) dental extraction and bone remodeling at anterosuperior region; (6) maxillary dental remodeling; (7) anterior-inferior dental extraction; (8) bone ridge remodeling; (9) implant fixation in interforaminal region; (10) mandibular complete denture capture as an overdenture, immediate charge. After 90 days, all necessary redeployment was done. Results:  The patient had a three-year regular follow-up, he had always shown satisfaction with the results. Conclusion: Adopting this protocol was effective to rehabilitate the patient with serious oral impairment.   Descriptors: Immediate Complete Denture. Life Quality
