The Use of Osseodensification for Ridge Expansion and Dental Implant Placement in Narrow Alveolar Ridges: A Prospective Observational Clinical Study.

ABSTRACT: The osseodensification (OD) drilling technique was suggested as an alveolar ridge expansion technique, so the aim of this prospective clinical study was to evaluate the amount of bone expansion obtained by the OD drilling technique and its effect on implant stability in patients with narrow alveolar ridges. The width of the alveolar ridge was measured at the crest before and after implant site preparation, whereas the implant stability was measured using Osstell Beacon implant stability quotient (ISQ). The ISQ values were recorded immediately postoperatively and after 16 weeks. Twenty-three patients were included; they received 40 implants. The mean (± standard deviation [SD]) amount of expansion was 1.29 (± 0.41) mm, and the difference between preexpansion and post-expansion bone width was statistically significant ( P < 0.001). The mean (± SD) primary stability was 73.73 (± 2.85) ISQ, whereas the mean (± SD) secondary stability was 74.83 (± 2.73) ISQ, and the difference was statistically significant ( P = 0.043). The implant survival rate was 100%. It can be concluded that using the OD technique in narrow alveolar ridges resulted in bone expansion without dehiscence or fenestration and allowed simultaneous implant placement with high primary and secondary implant stability.

Efectividad de un programa de rehabilitación respiratoria en pacientes con síndrome de apnea obstructiva del sueño: estudio cuasi-experimental / Effectiveness of a respiratory rehabilitation programme in patients with sleep obstructive apnoea syndrome: Quasi experimental study

OBJETIVOS: El objetivo del estudio fue analizar la efectividad de un programa de rehabilitación respiratoria en pacientes obesos sedentarios con síndrome de apnea obstructiva del sueño (SAOS) en el que se incluyó la realización de ejercicio físico terapéutico. Participantes y métodos: Estudio cuasi-experimental de 2 grupos, grupo intervención y grupo control, no aleatorizados con evaluación pre/post. Se seleccionaron 47 pacientes del hospital diagnosticados de SAOS con obesidad y en tratamiento médico, los cuales fueron tratados por el mismo equipo y siguiendo los mismos criterios diagnósticos. Se registraron las siguientes variables: índice de masa corporal, poligrafía respiratoria, capacidad de ejercicio, patrón de comportamiento sedentario y calidad de vida. Se realizó una comparación pre/post a los 3 meses. RESULTADOS: Se analizaron 38 pacientes y los resultados obtenidos al comparar los valores pre/post de todos los individuos muestran diferencias significativas en forma de mejora en todas las variables analizadas a excepción del comportamiento sedentario. En la comparación pre/post entre los grupos se aprecia una diferencia significativa (p = 0,049) en la percepción de la calidad de vida, concretamente, en la dimensión de los síntomas diurnos (0,42; IC 95%: 0,48-1,33), indicando una tendencia a la mejora en el grupo que ha realizado el programa de ejercicio propuesto. CONCLUSIÓN: La combinación del tratamiento médico de los pacientes durante un mínimo de 6 meses junto con la realización del programa de rehabilitación respiratoria en el que se incluye el ejercicio físico terapéutico genera una tendencia a la mejora clínica de estos, aumentando su calidad de vida, pero sin ningún tipo de cambio en su comportamiento sedentario

OBJECTIVES: The objective of the study was to analyse the effectiveness of a respiratory rehabilitation programme in sedentary, obese patients with Obstructive Sleep Apnoea Syndrome (OSAS) which included therapeutic physical exercise. Participants and methods: A quasi-experimental study of two groups, an intervention group and a control group, not randomised and with pre/post evaluation. Forty-seven hospital patients diagnosed with obesity and under medical treatment were selected and treated by the same team, following the same diagnostic criteria. The following variables were recorded: body mass index, respiratory polygraph, exercise capacity, sedentary behaviour pattern and quality of life. A pre/post comparison was made at 3 months. RESULTS: 38 patients were analysed, and the results obtained when comparing the pre/post values of all the individuals show significant differences in the form of improvement in all variables analysed except for sedentary behaviour. In the pre/post comparison between the groups, a significant difference (p=.049) was observed in perception of quality of life, specifically in the daytime symptom dimension (.42; 95% CI: .48-1.33), indicating a trend towards improvement in the group that undertook the proposed exercise programme. CONCLUSION: The combination of the patients' medical treatment over a minimum of 6 months together with completion of the respiratory rehabilitation programme which included therapeutic physical exercise resulted in a tendency to clinical improvement for the patients, increasing their quality of life, but with no change in their sedentary behaviour
