Skeletal class II has always been a challenge in orthodontics and often needs assistance of surgical orthodontics in nongrowing\npatients when it presents with severe discrepancy. Difficulty increases more when vertical dysplasia is also associated with sagittal\ndiscrepancy. The advent of mini implants in orthodontics has broadened the spectrum of camouflage treatment. This case report\npresents a 16-year-old nongrowing girl with severe class II because of retrognathic mandible, and anterior dentoalveolar protrusion\nsagittally and vertically resulted in severe overjet of 13mmand excessive display of incisors and gums. Both maxillary central incisors\nwere trimmed by general practitioner few years back to reduce visibility. Treatment involved use of micro implant for retraction and\nintrusion of anterior maxillary dentoalveolar segment while lower incisors were proclined to obtain normal overjet, and overbite\nand pleasing soft tissue profile. Smile esthetics was further improved with composite restoration of incisal edges of both central\nincisors....
The aim of the present case report is to describe the orthodontic-surgical treatment of a 17-year-and-9-month-old female patient\nwith a Class III malocclusion, poor facial esthetics, and mandibular and chin protrusion. She had significant anteroposterior and\ntransverse discrepancies, a concave profile, and strained lip closure. Intraorally, she had a negative overjet of 5mm and an overbite\nof 5 mm. The treatment objectives were to correct the malocclusion, and facial esthetic and also return the correct function. The\nsurgical procedures included a Le Fort I osteotomy for expansion, advancement, impaction, and rotation of the maxilla to correct the\nocclusal plane inclination. There was 2mmof impaction of the anterior portion of the maxilla and 5mmof extrusion in the posterior\nregion. A bilateral sagittal split osteotomy was performed in order to allow counterclockwise rotation of the mandible and anterior\nprojection of the chin, accompanying the maxillary occlusal plane. Rigid internal fixation was used without any intermaxillary\nfixation. It was concluded that these procedures were very effective in producing a pleasing facial esthetic result, showing stability\n7 years posttreatment....
Pseudo-Class III malocclusion is characterized by the presence of an anterior crossbite due to a forward functional displacement of\nthemandible; in most cases, the maxillary incisors present some degree of retroclination, and themandibular incisors are proclined.\nVarious types of appliances have been described in the literature for the early treatment of pseudo-Class III malocclusion. The\nobjectives of this paper are to demonstrate the importance of making the differential diagnosis between a skeletal and a pseudo-\nClass III malocclusion and to describe the correction of an anterior crossbite. The association of maxillary expansion and a 2 Ã?â?? 4\nappliance can successfully be used to correct anterior crossbites...
There has always been concern in determining the relationship between orthodontic toothmovement and the consequent biological\ncosts to the periodontium and tooth root. The possibility of evaluating the tooth and bone morphology by CBCT allows more\naccurate analysis of qualitative and quantitative aspects of these processes. This paper presents a case report of a 20-year-old male\npatient with Class III malocclusion and hyperdivergent facial pattern, who was surgically treated. A significant amount of labial\nmovement of mandibular incisors was performed during orthodontic treatment before surgery. CBCT was used for evaluation\nof buccal and lingual bone plates before and after tooth decompensation. The changes in the bone insertion level of maxillary\nand mandibular incisors in the present case encourage a reflection on the treatment protocol in individuals with dentoskeletal\ndiscrepancies....
Dental trauma can lead to a wide range of injuries of which crown and root fractures are examples. Crown-root fractures often need\ncomplex treatment planning. This case report describes the use of MTA in the multidisciplinary management of a patient with a\nhorizontally fractured central incisor and luxation in a different central incisor. A 42-year-old female patient presented within 1 h\nof receiving direct trauma to her maxillary area. Clinical examination revealed that the right and left maxillary central incisors\npresented mobility and sensitivity to percussion and palpation but no sensitivity to thermal stimulations. Occlusal displacement\nwith extrusion in the left maxillary central incisor and luxation in the right maxillary central incisor was observed. Radiographic\nexamination revealed horizontal root fracture at the apical third of the left maxillary central incisor. Root fracture in the right\nmaxillary incisor was not observed. Endodontic and aesthetic restorative treatments were completed. MTA showed a good longterm\noutcome when used in root-fractured and luxated teeth. In addition, composite resin restoration provided satisfactory\naesthetic results even after 15 months....
When the posteriormaxilla is atrophic, the reference standard of care would be to performsinus augmentation with an autologous\nbone graft through the lateral approach and delayed implant placement. However, placement of short implants with the osteotome\nsinus floor elevation technique andwithout graft can be proposed for an efficient treatment of clinical cases with a maxillary residual\nbone height of 4 to 8 mm. The use of grafting material is recommended only when the residual bone height is ?4 mm. Indications\nof the lateral sinus floor elevation are limited to cases with a residual bone height ? 2mm and fused corticals, uncompleted healing\nof the edentulous site, and absence of flat cortical bone crest or when the patient wishes to wear a removable prosthesis during the\nhealing period. The presented case report illustrates osteotome sinus floor elevation with and without grafting and simultaneous\nimplant placement in extreme conditions: atrophic maxilla, short implant placement, reduced healing time, and single crown\nrehabilitation. After 6 years, all placed implants were functional with an endosinus bone gain....
Theaimof this study was to achieve aesthetically pleasing soft tissue contours in a severely compromised tooth in the anterior region\nof the maxilla. For a right-maxillary central incisor with localized advanced chronic periodontitis a tooth extraction followed by\nreconstructive procedures and delayed implant placement was proposed and accepted by the patient. Guided bone regeneration\n(GBR) technique was employed,with a biphasic calcium-phosphate (BCP) block graft placed in the extraction socket in conjunction\nwith granules of the same material and a resorbable barrier membrane. After 6 months of healing, an implant was installed.\nThe acrylic provisional restoration remained in situ for 3 months and then was substituted with the definitive crown. This ridge\nreconstruction technique enabled preserving both hard and soft tissues and counteracting vertical and horizontal bone resorption\nafter tooth extraction and allowed for an ideal three-dimensional implant placement. Localized severe alveolar bone resorption\nof the anterior maxilla associated with chronic periodontal disease can be successfully treated by means of ridge reconstruction\nwith GBR and delayed implant insertion; the placement of an early-loaded,Morse taper connection implant in the grafted site was\neffective to create an excellent clinical aesthetic result and to maintain it along time....
Background: The aim of this cross-sectional study was to evaluate the impact of oral health conditions, socioeconomic\nstatus and use of specific substances on quality of life of alcohol and drug addicted persons, receiving care at outpatient\ntreatment facilities in Brazil.\nMethods: A random sample of 262 participants, mean age 37 years, from Psychosocial Care Centers for Alcohol and\nDrugs (CAPS AD) located in three cities in the state of S�£o Paulo, Brazil, were clinically examined for caries experience\n(DMFT index) by a calibrated examiner. They were asked to complete a series of questionnaires, including the Alcohol,\nSmoking and Substance Involvement Screening Test (ASSIST), socioeconomic characteristics, and the World Health\nOrganization Quality of Life assessment (WHOQOL), which were considered the outcome variables of the study.\nAssociations between oral health status, socioeconomic characteristics, substance involvement with WHOQOL\nwere investigated by means of the chi-square test and multiple logistic regression analysis with a level of significance\n? < 0.05.\nResults: The mean DMF index of the group was 13.0. Subjects with DMFT >14 (OR = 2.25; CI 95% = 1.30-3.89);\nlow-income (OR = 2.41; CI 95% = 1.22-4.77) and users of cocaine/crack (OR = 2.02; CI 95% = 1.15-3.59) were more\nlikely to have poor general quality of life.\nConclusion: This study demonstrated that the general quality of life of addicted persons was associated with caries\nexperience, low income and cocaine/crack use....
