Os sentidos da cirurgia estética: utilidade, futilidade, agência e/ou incorporação

This article aims to reflect on the growth of the practice of plastic surgery for cosmetic purposes and its relationship with the contemporary consumer culture. In other words, we discuss how this practice expresses the values and principles for consumer culture and configures itself differently in different contextsin, as the cities of Sao Paulo and London, where he held field work involving the collection of information in press materials, data files, interviews and observation in clinical aes‐ thetic.

Avaliação anteroposterior da posição da mandíbula em crianças dolicofaciais com má oclusão Classe II, divisão 1 de Angle

In this study, it is proposed to evaluate the anteroposterior position of mandible in children with Angle Class II, division 1 malocclusions, to compare two different methods of evaluating the jaw position and verifying the correlation between these two methods. We selected 26 Brazilian children with vertical growth pattern and Angle Class II, division 1 malocclusions, aged between 7 years and 8 months to 9 years and 6 months. The evaluation of the anteroposterior position of the mandible was performed with the use of lateral cephalograms by cephalometric angular SNB and linear Pog-Nperp. Based on the results obtained, it was concluded that the SNB identified more children with mandibular retrusion than Pog-Nperp; the increased tip of the SN plane may have decreased values of SNB; Pog-Nperp minimizes the possibility of error in the anteroposterior position of the mandible, since it eliminates the variable tip of the anterior skull base (SN plane); none of the cephalometric measurements used are able to eliminate the influence of the nasion point in the anterior-posterior and vertical position; correlation between SNB and Pog-Nperp is very low.

Camuflagem ortodôntica com dispositivos de ancoragem temporários ou cirurgia ortognática: parâmetros para a decisão

The polemical discussion between orthodontic therapeutic and surgical approaches with relation to borderline cases receives a new impulse with the emergence of temporary anchorage devices. This branch of Orthodontics has brought new treatment perspectives, but it has still been applied empirically, while the various factors involved in determining and conducting the treatment planning are neglected. The objective of the present study is to identify the several factors to be considered in both forms of treatment in order to provide the orthodontist with information that may contribute for the correct decision.

Estabilidade sagital da condiloplastia associada à cirurgia ortognática para o tratamento do osteocondroma mandibular

The aim of this study was to evaluate the stability of the conservative condylectomy technique and articular disc repositioning as the surgical treatment approach for management of mandibular condylar osteochondroma, with appropriate Orthognathic surgery. Fifteen patients (12 females and 3 males), average age of 32.3 years (range, 13 to 56 years), with unilateral active osteochondroma of the mandibular condyle were analyzed. All patients underwent conservative condylectomy, recontouring of the remaining condylar neck stump and articular disc repositioned and indicated orthognatic surgical procedures. Average post surgical follow-up was 19 months. Each patient's lateral cephalograms were traced at 3 intervals (presurgery, immediate post surgery and long-term follow-up). Immediate after surgery the oclusal plane angle decreased -2.8 ± 4.5o, the maxillomandibular complex rotated counter-clockwise with advancement at menton 5.3 ± 5.6 mm, pogonion 5.0 ± 5.1 mm, B point 3.4 ± 4.2 mm and A point 1.0 ± 1.5 mm. The long-term follow-up showed significant changes in overbite (-0.6 ± 0.5 mm) and SNGoMe (0,93° ± 1,53°). Horizontally and vertically small instabilities occurred in Me (-1.21 ± 1.94 mm) and PNS (-1.48 ± 1.67 mm) respectively. The treatment protocol studied produced counterclockwise rotation and maxillofacial mandibular advancement. The long-term follow-up showed solid dental and skeletal stability with horizontal instability of Me and PNS in the vertical direction.

Prevalência de alterações sistêmicas em pacientes atendidos na disciplina de cirurgia e traumatologia bucomaxilofacial do curso de Odontologia da UNIARA

Introduction: pre-operative assessment is of fundamental importance for the prevention of transoperative and of postoperative complications. Objective: to identify the prevalence of diseases and systemic conditions in patients undergoing surgical treatment in the discipline of surgery and Traumatology of University Center of Araraquara, in the period of 2004 to 2009. Material and method: for the development of this study, a survey in medical records of patients was performed and the factors considered included: age, sex, presence of vices, and systemic conditions that affect the world’s population. The data obtained were analyzed quantitatively and recorded in a table. Result:  Considering all patient records analyzed (693), 340 affirmative responses were detected (49,06%) to one or more diseases. Cardiovascular diseases were the most prevalent (22,34%). Considering the prevalence of diseases related to age, the age of less than 20 years represented 16,32%; of 20-29 years, 43,06%; 30-39 years, 45,16%; 40-44 years, 48,64%; 45-49 years, 56,25%; 50-54 years, 58,33%; 55-59 years, 57,74%; 60-64 years, 70,37%; 65-69 years, 66,66%; and 70 years or more, 68,75%. Conclusion: diseases and systemic alterations with higher prevalence were cardiovascular diseases, anemia, sinusitis and diabetes. The frequency of affirmative answers to systemic conditions was age-dependent and there was a predominance of females. The tobacco addiction was the most frequent. Thus, it was found that the preoperative assessment of the health of patients who will undergo surgical dental treatment is of fundamental importance.

Avaliação radiográficada fusão das corticias lateral e medial do ramo mandibular: estudo em mandíbulas secas

Purpose: to radiographically evaluate the distance between mandibular lingula and the exact spot where buccal and lingual cortical bone plates merge in the mandibular ramus. Materials and Methods: 54 dry mandibles, divided into 3 subgroups (SG1: dentate, SG2: partially dentate and SG3: edentulous) were used in this study. Lingula position was marked with a metallic sphere and radiographs were taken. The distance between mandibular notch and lingula (I/L) and the distance between mandibular lingula and cortical bone plates fusion (L/FC) were measured. Statistical analysis was applied to the values obtained. Results: mean values for L/FC were 8,18mm, 7,30mm and 8,98mm for SG1, SG2 e SG3 respectively. Moreover, mean values for I/L were 14,02mm, 13,90mm and 12,34mm for SG1, SG 2 and SG3 respectively. The results also showed that cortical bone plates fusion took place in half I/L distance in 28,57% of the mandibles in SG1, in 46,67% of the mandibles in SG2 and in 9,09% of the pieces in SG3. Conclusions: there were no statistically significant differences in the height where cortical bone plates took place in all 3 subgroups. In SG3, the correlation between the mean value for L/FC and the mean value for I/L suggests a reduction in bone density and bone mass, which can correlate to the evaluation of older mandibles in this subgroup.

Implantes curtos em região posterior da mandíbula

The rehabilitation of edentulous areas with osseointegrated dental implants is a well-documented, predictable procedure in the literature, with high success rates. However, the lack of bone at the recipient bed or proximity to anatomic structures limits the rehabilitation procedure especially at the posterior mandible. Thus, short implants are an alternative treatment for such cases of severe bone resorption. The purpose of this study was to review the success rate of short implants, especially those based in the posterior mandible and to show a clinical case. A literature review was made on electronic databases PubMed and Bireme with articles published between the years 2005 to 2012, using the keywords "short dental implants". It was concluded that the success rates of short implants are similar to those presented by conventional implants but still related to their geometry and surface treatment. Also, short implants can be considered as a viable alternative for the rehabilitation of severely resorbed jaws. However, many authors consider that more research is necessary when a short implant is compared to a long dental implant.

Tratamento cirúrgico de tumor odontogênico queratocístico: relato de caso

Introduction: The Keratocystic Odontogenic Tumor (KCOT) is a benign odontogenic tumor with an infiltrative and potentially aggressive behavior with high recurrence rates. The KCOT occurs more often in men than women, with a frequency of 2:1, being more frequent in the mandible with a predilection for the body and branch. Treatment of KCOT remains controversial. Treatment usually includes enucleation, marsupialization, peripheral ostectomy, curettage associated with Carnoy solution and resection. Objective: To report a case of a KCOT located in the mandible. Case report: male patient, 15 years, with a KCOT on the right side of the mandible treated by enucleation and peripheral ostectomy, with four years of preservation, with no signs of recurrence. Final Comments: The treatment by enucleation associated with peripheral ostectomy reduces the relapse rate, preserves anatomical structures and can avoid a second surgical procedure for reconstruction of bone defects generated in surgery en bloc resection.

Complicações Associadas aos Enxertos Ósseos Aposicionais com Osso Autógeno

Introdution: Tooth extraction results in alveolar ridge resorption due to the progressive reabsorption, which frequently is a limitating factor of dental implants treatment, in function of the insufficient bone height for execution, could be indicated the use of grafts for increase of the alveolar edge. However, the success of the bone graft requests the meticulous attendance of the clinical stages. Proposition: The objective of this research was to evaluate the postoperative complications associated to the autogenous bone grafts. Materials and Methods: Through a random retrospective analysis, 90 file records of patients submitted to the surgical procedure of autogenous bone graft in the period of January from 2000 to the March of 2008. A clinical record was elaborated with base in the necessary data for this evaluation. Results: About the file data analysis, 59 female with average of 49,42 years and 31 male with average of 47,90 years. The previous diseases most related were arterial hypertension, stomachache and diabetis. The smokers was noticed in 13,3% of patients. The donor site most used was a mandibular ramus. The postoperative complications in receiving area represented 17,8% of file datas analysed and in the donor site only one patient showed parestesis. Conclusion: Among the total analyzed files it was observed that the postoperative complications associated with the autogenous bone grafts represented 18,9% of the patients submitted to the procedure, more frequently affecting the receiving area, obtaining partial exposure of the bone graft and absence of inserted gingiva on vestibular cortical bone.

Cirurgia estética para remoção de hiperplasia gengiva: granuloma piogênico

The pyogenic granuloma, a lesion considered hyperplastic regenerative inflammatory reaction is a finding commonly found in the oral cavity, affecting large numbers of individuals, being more prevalent in females. But its pathogenesis is not well defined and may be associated with numerous factors that stimulate tissue proliferation. Correct diagnosis and treatment plan are essential for success in approach, restoring function and aesthetics to the periodontal tissues. In agreement with the literature, the most common treatment and greater predictability is surgical removal, which involves resection of the lesion, together with its base inserted into the underlying tissue, periosteum and bone tissue. However, the excision can promote aesthetic defects, particularly in anterior regions where it is most affected. This article reports on the importance of a correct surgical approach for removal of pyogenic granuloma in the region of the interdental papilla between teeth 42 and 43, resulting in a good anatomical result and aesthetic.

Estudo anatomico da posição do forame mandibular e da língula em mandíbulas secas

Purpose: The authors tried to verify the anatomic location of the mandibular foramen and língula in dry jaws regarding the anterior and posterior border of the mandible and the incisure, alveolar border and mandibular base, in order to correlate the data with the sagittal split ramus osteotomy. Methods: There were evaluated 44 mandibles (88 sides) from the Morphology Department of the Araraquara Dental School of the São Paulo University (UNESP). The distances measured were previously deter - mined according to the figures presented in this article and were done by the use of a sliding caliper (Brow & Sharpe Digit-Cal Plus), with the mandibles positioned over a Erickson table, and the distan - ces were always measured in millimeters. Results: The pre-determined points and distances founded were X=17,67; Y=14,35; W=20,96 and Z=21,89 for the mandibular foramen, and the relationship between this anatomical structure and the língula shows that the mandibular foramen is in average 5,82 mm below the língula. Conclusions: The authors conclude that the mandibular foramen is lightly posterior in comparison with the ramus mandibular center and that the língula is a very important anatomic landmark for the ramus surgeries as well the knowledge of the distance between it and the mandibular foramen entrance.
