Lowering of the mouth floor and vestibuloplasty to support a mandibular overdenture retained by two implants: a case report

In Oral Implantology most of the procedures are predictable and have high success rates. The use of osseointegrated implants as a therapeutic option for the rehabilitation of patients with severe mandibular atrophy has decreased the need for pre-prosthetic surgery Nevertheless, complications may occur during implant surgery and also once the prosthesis has been placed. This paper describes the case of a totally edentulous patient with an upper complete removable denture and an implant-retained overdenture with two implants in the intermentonian region. During clinical examination, the implant abutments were totally covered by soft tissue since the floor of the mouth was elevated. The panoramic radiography showed severe mandibular atrophy. Vestibuloplasty was performed together with the lowering of the floor of the mouth under general anesthesia and nasotracheal intubation to expose the implants. A new prosthesis was fabricated for the patient to prevent recurrence and improve the patient's chewing ability as it formed a physical barrier against soft tissue migration on prosthetic attachments

Traumatic bone cyst: a retrospective study of 21 cases

Objective: To describe the clinical and radiological characteristics, and surgical findings of traumatic bone cysts.Study Design: A retrospective observational study was made of 21 traumatic bone cysts. The diagnosis was based on the anamnesis, clinical examination, and complementary tests. Panoramic and periapical X-rays were obtained in all cases, together with computed tomography as decided by the surgeon. A descriptive statistical analysis was made of the study variables using the SPSS v12.0 for Windows.Results: There was a clear female predominance (14:7). The mean age was 26.5 years (range 8-45 years). The cysts in all cases constituted casual findings during routine radiological exploration. In those cases where computed tomographic images were available, preservation of the vestibular and lingual cortical layers was observed. Five of the 21 patients (23.8%) reported a clear antecedent of traumatism in the affected zone. All the lesions were subjected to surgery, and the cavities were found to be vacant in 90.5% of the cases. In only two patients were vascular contents seen within the cavity. Two of the patients presented postoperative paresthesia of the inferior dental nerve that subsided within two weeks. The 19 patients in whom adequate postoperative follow-up proved possible all showed complete bone healing.Conclusions: Traumatic bone cysts were a casual finding. During the surgery, most cases showed to be vacant cavity without an ephitelial lining. Careful curettage of the lesion favors progressive bone regeneration, offering a good prognosis and an almost negligible relapse rate. Other treatment options only would be justified in cases of relapse

Revisión bibliográfica de implantología bucofacial del año 2008. Primera parte

La actividad asistencial de los profesionales de la Odontología tiene como consecuencia una baja disponibilidad de tiempo para dedicarse a la lectura de artículos científicos. Ante la dificultad de mantener un buen nivel de información en el campo de la Implantología Bucofacial, nuestro interés es exponer de forma sintética una revisión de la literatura científica publicada en las revistas más relevantes de la especialidad durante el año 2008. El lector interesado encontrará en este artículo algunos de los diferentes temas que integran esta disciplina, expuestos por apartados (plan de tratamiento, pacientes especiales, diseño y superficies, regeneración ósea, regeneración tisular guiada, carga inmediata, pacientes irradiados, implantes extraorales)

Regeneración tisular guiada mediante membranas reabsorbibles de colágeno tras la extracción quirúrgica del tercer molar inferior incluido. Ensayo clínico randomizado a doble ciego.

[spa] OBJETIVOS: El uso de membranas de colágeno reabsorbibles (MBM) en el tratamiento de defectos intraóseos y bolsas periodontales profundas en la cara distal del segundo molar inferior (2MI) después de la extracción quirúrgica de un tercer molar inferior impactado (3MI) ha mostrado resultados contradictorios. Este estudio evaluó los efectos de la colocación de MBM en la curación de un defecto óseo distal al 2MI después de la extracción quirúrgica de los 3MI incluidos en posición horizontal o mesioangular. PACIENTES Y MÉTODOS: Se llevó a cabo un ensayo controlado aleatorio de grupos paralelos con 2 grupos independientes de 30 pacientes que requieren la extracción quirúrgica de un 3Mi. Después de la extracción, los pacientes recibieron una MBM (Bio-Gide, Geistlich Pharma AG, Wolhusen, Suiza) o sólo sutura. En el control inicial y durante la monitorización postoperatoria al 1, 3 y 6 meses, se midió la profundidad de sindaje distovestibular, distal y distolingual, así como el nivel de inserción vestibular del 2MI. RESULTADOS: La edad (grupo control, 33,8 ± 6,9 años; grupo regeneración tisular guiada, 35.6 ± 6.3 años; p = 0,322) y el número de mujeres (grupo de control, 15 de 29; grupo regeneración tisular guiada, 14 de 27, p =. 992) fueron similares en los 2 grupos. Las profundidades de sondaje distovestibular, distal y distolingual y el relleno del defecto infraóseo mostraron una mayor mejoría a los 6 meses después de la extracción quirúrgica en el grupo MBM ( P <0,05). CONCLUSIONES: El uso de la MBM después de la extracción quirúrgica de 3MI en posición mesioangular u horizontal estimula la regeneración ósea, mejora el nivel de inserción y el relleno óseo distal al 2MI. Del mismo modo, disminuye la profundidad de sondaje distal y da como resultado una recuperación más rápida. La colocación MBM después de la extracción quirúrgica de un 3MI impactado es recomendable porque previene defectos periodontales después de la cirugía del 3MI[eng] PURPOSE: The use of resorbable collagen membranes (RMs) in the treatment of intraosseous defects and deep periodontal pockets on the distal side of a lower second molar (L2M) after surgical extraction of an impacted lower third molar (L3M) has shown contradictory results. This study evaluated the effects of RM placement on the healing of a bone defect distal to an L2M after surgical extraction of a horizontal or mesioangular impacted L3M. PATIENTS AND METHODS: A parallel-group randomized controlled trial with 2 independent groups of 30 patients requiring surgical extraction of an L3M was carried out. After extraction, patients received an RM (Bio-Gide, Geistlich Pharma AG, Wolhusen, Switzerland) or only suture. At the initial checkup and during postoperative monitoring at 1, 3, and 6 months, the distal vestibular, distal, and distolingual probing depths and distal vestibular attachment level of the L2M were measured. RESULTS: Age (control group, 33.8 ` 6.9 yr; guided tissue regeneration group, 35.6 ` 6.3 yr; P = .322) and the number of women (control group, 15 of 29; guided tissue regeneration group, 14 of 27; P = .992) were similar in the 2 groups. The distal vestibular, distal, and distolingual probing depths of the L2M, distal vestibular attachment level, distance from the cementoenamel junction, and distance from the alveolar crest to the base of the defect showed greater improvement 6 months after surgical extraction in the RM group (P < .05). CONCLUSIONS: The use of RMs after surgical extraction of mesioangular or horizontally impacted L3Ms stimulates bone regeneration, improving the attachment level and bone fill distal to the L2M. Likewise, it decreases the distal probing depth and results in faster recovery. RM placement after surgical extraction of an impacted L3M is recommended because it prevents periodontal defects after L3M surgery

Validation of a computer-assisted system on classifying lower third molars

Objectives: The present study evaluates the reliability of the Radio Memory® software (Radio Memory; Belo Horizonte,Brasil.) on classifying lower third molars, analyzing intra- and interexaminer agreement of the results. Study Design: An observational, descriptive study of 280 lower third molars was made. The corresponding orthopantomographs were analyzed by two examiners using the Radio Memory® software. The exam was repeated 30 days after the first observation by each examiner. Both intra- and interexaminer agreement were determined using the SPSS v 12.0 software package for Windows (SPSS; Chicago, USA). Results: Intra- and interexaminer agreement was shown for both the Pell & Gregory and the Winter classifications, p<0.01, with 99% significant correlation between variables in all the cases. Conclusions: The use of Radio Memory® software for the classification of lower third molars is shown to be a valid alternative to the conventional method (direct evaluation on the orthopantomograph), for both clinical and investigational applications

Antibiotic prescription in the treatment of odontogenic infection by health professionals: a factor to consensus

Objective: To observe the attitude of dentists and family doctors in prescribing antibiotics for the treatment of dental infections. Study Design: A poll was performed to determine the differences in the prescription of antibiotics for the treatment of odontogenic infection by dentists and family doctors of the primary care department of the Catalan Health Care Service. Results: A hundred polls were distributed among family doctors, and another 100 ones among primary care dentists assigned to the Catalan Health Care Service of the Generalitat de Catalunya. Of the total of questionnaires distributed, 63 were retuned and answered from dentists and 71 from family doctors. Eighty-one percent of dentists included in the opinion poll considered amoxicillin as the first antibiotic choice for the treatment of odontogenic infections, while 73.2% of family doctors preferred the combination of amoxicillin and clavulanic acid. With regard to antibiotics of choice in patients allergic to penicillin, 67.7% of family doctors preferred macrolides (25.4% opted for clarithromycin, 25.4% for erythromycin and 16.9% for spiramycin). However, clindamycin was the antibiotic most frequently prescribed by dentists (66.7%), followed by erythromycin (28.6%). Conclusions: The results of this study show a large discrepancy in the criteria for the treatment of odontogenic infections on the part of leading professionals involved in the management of this condition. Although the most common prescription involved beta-lactam antibiotics in both groups, several significant differences have been detected with regard to the second antibiotic choic
