Raiz dentária impelida para o seio maxilar após exodontia: uma opção de tratamento

Introduction: Upper teeth, especially first premolars and molars, can have a close anatomical relationship with the floor of maxillary sinus. For this reason, accidental displacement of dental roots into the sinus could happen during exodontic procedures. Objective: Description the treatment performed to remove a tooth root within the maxillary sinus, displaced during an extraction procedure. Case Report: Female patient, 39 years of age, which reported being subjected to the extraction of the element 26 for about two months. The patient was reported by the practitioner who performed the extraction that a root was pushed into the maxillary sinus. The treatment plan included surgery to remove the root within the maxillary sinus. Final Comments: Clinicians should be careful during extractions, to prevent these accidents. However, if such complications occur, access to the maxillary sinus is the best treatment option.

Atresia maxilar em adultos: simplificação da técnica cirúrgica

A expansão rápida da maxila cirurgicamente assistida (ERMCA) é realizada por meio de osteotomias nos pilares da maxila e na sutura palatina mediana, promovendo a correção da deficiência transversa da maxila. Técnicas menos invasivas foram descritas, visando à realização desses procedimentos sob anestesia local, eliminando os custos de internação hospitalar e trazendo maior conforto aos pacientes. A proposta deste trabalho foi discutir os aspectos envolvidos na simplificação da técnica da ERMCA sob anestesia local por meio do relato de caso clínico-cirúrgico de paciente com 27 anos de idade. Conclui-se que o diagnóstico por meio da avaliação clínica e dos modelos de estudo é essencial para a indicação da ERMCA e esse procedimento proporciona boa previsibilidade na correção da deficiência transversal, com mínima morbidade. Além disso, a utilização de uma técnica minimamente invasiva é efetiva no tratamento de maxilas atrésicas, com índices de recidiva semelhantes aos das técnicas mais invasivas.

Reabilitação protética implantossuportada em região anterior maxilar com utilização de gengiva artificial cerâmica: relato de caso

The osseointegrated implants created a progress in oral rehabilitation. But this rehabilitation may be complicated by anatomical conditions, mainly in maxillary anterior region, where a higher aesthetic is required. The aim of study was to report one case which the use of angled abutments were necessary to allow the correct positioning of the prosthesis and also the prosthetic reconstruction with gingival-colored ceramic to provide best aesthetic result for patient. The aesthetic and functional results provided greater patient satisfaction with her smile. The correct planning is essential to provide to patient the best aesthetic and functional results, being necessary the use of abutments and gingival-colored ceramic to reach better results. Uniterms: dental implantacion, esthetics, mouth rehabilitation.

Deslocamento de implante dentário para o seio maxilar: relato de caso

The residual alveolar ridges may be unfavorable for implant placement. The edentulous maxilla is often challenging for the oral surgeon because of the lack of bone as a consequence of alveolar ridge resorption and/or maxillary sinus pneumatization. Accidents or complications may occur when some of these issues are not being known. This article reports one case of implant displaced into the maxillary sinus, 27 days after sinus bone augmentation with simultaneous dental implant installation, causing moderated sinusitis symptoms. The implant was removed through oral cavity access to maxillary sinus.

Parafunção severa: reabilitação oral com prótese total mandibular x overlay maxilar: relato de caso

In many oral rehabilitation professionals seeking venture renew people smile. However, these procedures have functional implications and aesthetic criteria which must be satisfied so that the final result is predictable. The restoration of relations intermaxillary, phonetics, masticatory function, esthetics and patient comfort are the goals to be achieved. An effective way to achieve these goals when immediate reconstruction with permanent dentures is not possible, make use of a type of partial denture called overlay. Bruxism is a manifestation of biopsychological imbalance that affects the stomatognathic system, characterized by clenching and / or attrition of teeth together so centric or eccentric, can be manifestation of nocturnal or diurnal. Its effects can manifest themselves in different parts of the stomatognathic system, varying the severity of the damage as the resistance of the structures affected, the time of existence, its regularity and the general state of the wearer. The description of the steps followed in solving this case, in which the patient edentulous mandibular arch while the maxillary arch showed absence of teeth 16 and 26 and, except for the teeth 17 and 27, all other teeth showed wear very sharp in the sense denoting incisal cervical, severe impairment of the vertical dimension, the quality of masticatory function and a marked impairment phonetic, this case report aims to guide the beginning of a rehabilitation, as well as the transitional phase of treatment for recovery of functional and aesthetic relationships intermaxillary .

Avaliação clínica e radiográfica de pacientes submetidos ao levantamento da membrana do seio maxilar

Implant dentistry is a dental specialty which presents great predictability in the rehabilitation at posterior, partially edentulous maxillary areas. Early tooth loss results in significant jaw remodeling. The maxillary sinus lifting followed by implant placement is a predictable technique initially described in 1980. Since then, several different techniques have been investigated varying filling materials and the management of complications in order to provide effective guidance in the rehabilitation of these patients. The current study evaluated ten patients who underwent sinus lifting before implant placement and crown installation. First, a retrospective analysis of the medical records was conducted to obtain information about possible postoperative complications. Clinical and radiographic analyses were performed at baseline and 180 days after surgeries. The sinus lifting with immediate implant placement provided satisfactory outcomes and can be considered a safe procedure. Treatment predictability was demonstrated in 90% of patients and for 86.96% of implants placed. It is important to highlight knowledge of anatomical structures at this area, the use of delicate surgical techniques, and strict patient follow-up.

Avaliação do índice de sucesso dos enxertos autógenos e dos implantes instalados em região de seio maxilar

Maxillary sinus lifting surgery is considered an excellent option for patient rehabilitation in cases of maxillary sinus pneumatization. This longitudinal study was performed in 41 patients to evaluate 51 maxillary sinus lifting procedures concomitant to autogenous bone grafted from mandibular ramus. Of the 107 implants installed, 28 were immediate fixations. Success index achieved regarding to bone graft was of 98.04%. The implants installed immediately or after bone grafting resulted in success rates of 92.86% and 94.59% respectively, with no statistically significant differences between them. Surgeries for bone grafting and immediate installation are considered a reliable treatment alternative provided that both anatomical structures and tissue physiology are kept in good conditions, with appropriate indication and techniques for good implant stability.

Responses to selection for milk traits in dairy buffaloes

The aim of the present study was to estimate the index and individual responses to selection for milk (MY), fat (FY) and protein (PY) yields for different breeding goals for two commercial buffalo milk production systems in São Paulo State characterized by: 1) all milk produced is sold to the industry (MILK) and 2) all milk produced is used in the mozzarella cheese-making process at the farm (MOZZARELLA). The current payment policy is based exclusively on milk volume. The mozzarella price refers to the wholesale selling price. Index responses to selection (IR) were calculated for three different breeding goals (BG): 1) MY exclusively (BG(1)); 2) FY + PY (BG(2)) and 3) MY + FY + PY (BG(3)). IR for the MILK system were US$ 41.79 (BG(1)), US$ 5.91 (BG(2)) and US$ 38.22 (BG(3)). For the MOZZARELLA system, IR were US$ 179.50 (BG(1)), US$ 262.85 (BG(2)) and US$ 402.41 (BG(3)). The results suggest that for the present circumstances, selection for milk components is not advantageous when milk is produced for sale to the industry. However, when mozzarella making is added to the system, the selection for components and milk volume is the most economically beneficial.
