Pérdida localizada de la superficie dental: enfoque de Dahl con restauraciones directas de resinas a mano alzada en el sector anterior. Informe de Caso

La pérdida de superficie dental se define como una condición en la que el desgaste de la estructura dental es excesivo según la edad. Esta pérdida patológica se relaciona comúnmente con una combinación de factores como erosión, abrasión, atricción o parafunción. La técnica de Dahl es una alternativa válida que resuelve los inconvenientes surgidos en este tipo de situaciones como ser la compensación dentoalveolar. Este caso corresponde a un paciente de 63 años que acudió al Hospital Dental de la Universidad de Manchester, derivado por su odontólogo particular. Al momento del examen clínico se constató pérdida moderada a severa de la superficie dental palatina e incisal localizada en el sector anterior de los dientes, sobremordida profunda y compensación alveolar dental. Fueron realizadas restauraciones directas a mano alzada de canino a canino. Luego del relleno incisal se constató una mordida abierta posterior de aproximadamente 1 a 1,5 mm. El contacto oclusal posterior fue restablecido totalmente en 3 meses.

Tooth Surface Loss (TSL) is defined as a condition in which the wear of the tooth structure is excessive according to age. This pathological loss is commonly related to a combination of factors such as erosion, abrasion, attrition, or parafunction. The Dahl technique is a valid alternative that solves the problems that arise in this type of situation, such as dentoalveolar compensation. This case describes a 63-year-old patient who attended the Dental Hospital of the University of Manchester, referred by his private dentist. At the time of the clinical examination, moderate to severe loss of the palatal and incisal tooth surface located in the anterior sector of the teeth, deep overbite and dental alveolar compensation were found. Direct free-hand restorations were performed from canine to canine. After incisal filling, a posterior open bite of approximately 1 to 1.5 mm was observed. Posterior occlusal contact was completely restored in 3 months.

Persistent Idiopathic Dentoalveolar pain. Literature review and clinical case treated with intraoral application of Botulinum toxin / Dolor Idiopático Dentoalveolar Persistente (DIDAP). Revisión de literatura y caso clínico tratado con aplicación intraoral de toxina Botulínica

ABSTRACT: Persistent Idiopathic Dentoalveolar Pain (PIDAP) is an orofacial neuropathic pain, which can be difficult to diagnose and is usually accompanied by increasing anxiety from both the patient and the treating dentist. A case of a 38-year-old female patient is presented, and it is shown the diagnostic process and therapeutic approach. The interdisciplinary management accompanied by several pharmacological lines is highlighted: Botulinum toxin was used as an adjunctive treatment allowing it to decrease systemically administered medications dosing and therefore its possible side effects. This condition usually affects psychosocial aspects of the patient and has a major impact on his quality of life. It is very important before initiating an invasive clinical treatment, obtaining a clear differential diagnosis and assessing in some cases the presence of non-odontogenic pain, such as PIDAP.

RESUMEN: El Dolor Idiopático Dentoalveolar Persistente (DIDAP), es un dolor neuropático orofacial, que puede resultar difícil de diagnosticar y generalmente se acompaña de creciente angustia tanto de parte del paciente como también del odontólogo tratante. Se presenta un caso de una paciente femenina de 38 años en donde se demuestra el proceso diagnóstico y abordaje terapéutico. Se resalta el manejo interdisciplinario acompañado de varias lineas farmacológica: la toxina Botulínica se utilizó como tratamiento coadyuvante para disminuir la dosis de medicamentos administrados por vía sistémica y por ende sus posibles efectos secundarios. Esta condición habitualmente abarca aspectos psicosociales del paciente y tiende a verse sumamente afectada su calidad de vida. Es de suma relevancia antes de iniciar un tratamiento clínico invasivo, obtener un diagnóstico diferencial claro y valorar en algunos casos la presencia de dolor no ontogénico, como el DIDAP.

A Cephalometric Evaluation of Anterior Deep Bite in Class II Malocclusions.

Background & objectives: Vertical malocclusions of the incisor teeth namely, anterior openbite and deep overbite present a challenge to the orthodontic clinicians. Determining the etiology of these is utmost important for further treatment planning and prognosis. Present study was carried out to understand the dentofacial skeletal pattern of the deep overbite in two types of deformities, Angle's Class II Div.l & Class II Div.2 (study group) and comparing them with normal occlusion (control group). Methods: Lateral cephalogram of total 60 pts, 20 in each of the above mentioned groups were analysed using 19 linear and 8 angular parameters and results of each group were compared with other two groups and conclusions were drawn. Result and conclusion: Larger posterior facial height, lower anterior facial height, lower gonial angle, larger Jaraback’s ratio & reduced lower molar height together contribute to horizontal growth pattern. It was concluded that there is more horizontal growth pattern in class II div. 2 cases hence the deepbite is more severe in class II div.2 cases compared to div.1 cases.

Uso de la regeneración ósea guiada (rog) con membranas biodegradables de co-polímeros en cirugía bucal para reparar defectos óseos: estudio clínico de 30 meses de seguimiento postquirúrgico

La regeneración ósea guiada (ROG) es frecuentemente usada para tratar defectos óseos pero muchas veces el tipo de membrana usada se degrada antes de que ocurra la adecuada cicatrización ósea y se introduce tejido blando en la zona a regenerar. El objetivo de éste estudio es evaluar la eficacia de usar el sistema de membranas y tachuelas biodegradables de co-polímeros en pacientes con defectos óseos o que necesiten levantamiento de membrana sinusal con un periódico control clínico y radiográfico. Este estudio fue realizado en 15 pacientes que tenían defectos óseos o necesitaban levantamiento de membrana sinusal, con un rango de edad entre 19 y 49 años con un promedio de 34 años de edad. 8 pacientes fueron femeninos y 7 masculinos. Se usó relleno óseo con las membranas y tachuelas biodegradables de co-polímeros en todos los casos, 7 de los casos fueron levantamiento de membrana sinusal y los otros 8 se trataron de defectos óseos. Se les realizó un seguimiento clínico y radiográfico cada 3 y 6 meses hasta 30 meses después del día de la cirugía entre los años 2005 y 2007, realizándose un análisis longitudinal. Se encontró que a 5 pacientes se les expuso la membrana, uno de ellos se mantuvo con enjuagues de clorhexidina hasta que cicatrizó por segunda intención, en 2 de los pacientes se les recortó y moldeó el borde expuesto y los otros 2 casos se tuvo que retirar la membrana y tachuelas por completo. Los 10 pacientes restantes cicatrizaron adecuadamente y no tuvieron ningún tipo de exposición, siendo el porcentaje de éxito al utilizar éste nuevo sistema de membranas y tachuelas biodegradables de co-polímeros del 66,7%. Se destaca que éste sistema de membranas y tachuelas biodegradables de co-polímeros no necesita ser retirado en una 2da cirugía. Debido al buen control postquirúrgico se pudo manejar de inmediato los casos donde hubo exposición de la membrana y sólo fracasaron 2 de 15. Se observó una adecuada cicatrización ósea tanto clínica ...

Guided bone regeneration (GBR) is frequently used to treat bone defects, however, most of the membranes degrade before bone healing has occurred permitting soft tissue invasion into the desired bone chamber. The aim of this clinical trail is to evaluate the efficacy of using a biodegradable co-polymers membrane and tacks system in patients with bone defects or need of maxillary sinus lift for implant placement with a long term clinical and radiographically follow up. All patients included in this study had the necessity of guided bone regeneration. 15 patients consisted of bone defects or the need of maxillary sinus lifting, with an age range of 19 to 49 years of age with an average of 34 years old. There were 8 females and 7 males. In all cases, we used biodegradable co-polymers membrane and tacks system that gets soft when applied but becomes rigid in-situ after approximately 15 minutes allowing the new bone cicatrization because it becomes a barrier for the bone grafting material, 7 patients underwent surgery for maxillary sinus lift and the other 8 for bone defects. Patients were followed clinical and radiographically during 3 to 6 months intervals up to 30 months between 2005 - 2007. A longitudinal study was performed by checking the patients clinical and radiographically during a continuously period of time up to 30 months postoperatively. 5 patients had partial membrane exposure, one of them was kept in clorhexidine mouth rinses and irrigation until secondary healing was accomplished. 2 patients were treated by cutting and trimming the membrane edges in order to get full mucosa coverage and it was obtained in 2 weeks after this procedure. In 2 cases the flap open totally and we had to remove the membrane. The rest 10 of the 15 patients healed uneventfully. The percentage of success using the biodegradable co-polymers membrane and tacks system was 66,7% . This biodegradable co-polymers membrane and tacks system does not require ...

The relationship between overjet size and dentoalveolar compensation.

Background : The purpose of this study was to investigate the effect of overjet size and the dento-alveolar compensation in subjects with normal class I molar relationship. Materials and Methods: Lateral cephalometric head records of 59 Egyptian children (34 boys and 25 girls) aged 7.5 to 10.5 years with mean age of 8.69±0.73. All had normal class I type of occlusion. The sample was classified into four quartiles according to the overjet size and the cephalometric analysis was based on seven linear and eight angular measurements using a dental tracer programme. Results: showed that, in spite of presence of high significant over jet size differences between the groups; there was no significant differences in all the studied parameters were found. Applying the least significant differences (LSD) test and coefficient correlations between the studied parameters clarifying that there was a significant differences in angular measurements (SN-AB, SN-Occl, I-I, I-ML, I-NB). Conclusion: during transitional dentition there was a sufficient dento-alveolar adaptation to growth changes in the saggittal jaw relation ship to attain normal class I type of occlusion. This compensation is pronounced in angular parameters and clustered in the lower arches particularly in incisal area.
