E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Principal objective: To compare linear changes in bone width between the tested interventions aimed for vertical and lateral bone augmentation; test (combination of autologous culture expanded mesenchymal stem cells and biomaterials) and control groups (autologous bone block graft from ramus fixed with osteosynthesis screws) |
Objetivo principal: comparar los cambios lineales en anchura ósea entre las intervenciones evaluadas para el aumento óseo horizontal y vertical; grupo test (combinación de células madre mesenquimales autólogas y biomaterials) y grupo control (injerto óseo en bloque de rama mandibular fijado con tornillos de osteosíntesis) |
|
E.2.2 | Secondary objectives of the trial |
(1) To evaluate efficacy of treatment and formation of new bone by: assessing the possibility to insert an implant 5 months after the grafting procedure (3D CBCT) Measuring clinical changes in alveolar bone width. evaluating the collected core biopsies using μCT, SRμCT and histology. evaluting outcomes after implant placement (2) To evaluate the safety of the interventions by: assessing adverse effects (AEs) and soft tissue healing at 2 and 4 weeks and 5 months assessing the morbidity associated with both procedures by measuring the usage of postoperative anti-inflammatory medication and degree of reported pain using a VAS scale assessing fate of the transplanted MSCs by liquid biopsy (blood samples and plasma/sera at screening and 2 weeks after bone augmentation surgery) (3) To assess patient’s satisfaction with surgical intervention and prosthetic outcome by patient reported outcomes (PROMs). Impact of treatment on the patient’s overall quality of life (QoL) will be assessed |
(1)Evaluar eficacia del tratamiento y formación de nuevo hueso mediante valoración de: a) Posibilidad de colocar un implante 5 meses tras procedimiento (CBCT 3D); b) medición de cambios clínicos en anchura del hueso alveolar. c) evaluación de biopsias de cilindros tomados (μCT, SRμCT e histología); c) evaluación variables tras colocación del implante dental. (2) Evaluar seguridad intervenciones mediante: a) valoración efectos adversos (EA) y cicatrización tejido blando a las 2 y 4 semanas y 5 meses, analizando morbilidad asociada, registrando uso de medicación postoperatoria anti-inflamatoria y grado del dolor reportado por paciente (escala VAS). b)Evaluar destino células MSCs transplantadas mediante biopsia líquida (muestras sangre y plasma/ suero en screening y 2 semanas tras cirugía). (3) Valorar satisfacción paciente con intervención quirúrgica y resultado prostodóncico mediante variables basadas en el paciente. Se analizará impacto tratamiento en calidad de vida paciente.

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
•Written informed consent Patient should be able to understand and complete the informed consent Age 18 years or older Insufficient bone ridge width (≤ than 4 mm) and or height at the recipient site for titanium dental implant placement Patient should be eligible for bone marrow harvest and bone transplant Healthy oral mucosa, at least 2 mm keratinized mucosa Female candidates of child bearing potential (WOCBP) -as defined by CTFG 2- must be referred to their physician for a pregnancy test 1,2 before inclusion in the study. In case of a negative preganancy test their physician will be asked to prescribe one of the highly effective birth control methods recommended by CTFG 2 which includes: 1. Combined estrogen and progestogen containing contraceptives that are associated with inhibition of ovulation (oral, intravaginal or transdermal). 2. Progestogen-only hormonal contraceptives associated with inhibition of ovulation (oral, injectable or implantable). 3. Intrauterine devices. 4. Intrauterine hormone-releasing system. 5. Bilateral tubal occlusion. The WOCBP candidates will only be included in the study if the pregnency tests are negative. These patients must continue using the contraceptives until the placement of dental implants (5 months after bone augmentation procedure considering that pregnancy is not considered as a contraindication for normal dental implant). Female candidates that have entered menopause for less than 12 months must also be referred to confirm post-menopausal state by testing the level of follicle stimulating hormone (FSH). |
* Consentimiento informado por escrito - El Paciente debe ser capaz de entender y completar el consentimiento informado. - Tener mínimo 18 años de edad - Anchura de cresta ósea insuficiente (<4mm) y/o altura en área receptora para la colocación de in implante dental de titanio. - El paciente debe poder ser elegible para la toma de médula ósea y transplante de hueso. - Mucosa oral sana, con al menos 2mm de mucosa queratinizada - Mujeres en edad fértil, definidas por CTFG 2-, deben ser referidas a su médico para que se les realice un test de embarazo 1,2 antes de su inclusión en el estudio. En caso de un test de embarazo negativo, se solicitará a su médico que le prescriba uno de los métodos recomendados altamente efectivos para el control de la natalidad por GTFG 2, que incluyen: 1. Anticonceptivos basados en estrógeno y progestágenos combinados, que estás asociados con la inhibición de la ovulación (oral, intravaginal o transdérmico) 2. Anticonceptivos basados en sólo progestágenos asociados con la inhibición de la ovulación (oral, inyectable o implantable) 3. Dispositivos intrauterinos. 4. Sistemas de liberación de hormonas intrauterino. 5. Oclusión tubal bilateral - Los candidatos de sexo femenino en edad fértil solo se incluirán en el estudio si los test de embarazo son negativos. Estos pacientes deberán continuar utilizando anticonceptivos hasta la colocación de los implantes dentales (5 meses tras el aumento óseo, considerando que el embarazo no es una contraindicación para los implantes dentales normales) - Los candidatos de sexo femenino que hayan entrado en menopausia en los últimos 12 meses deberán ser también referidos para confirmar el estado post-menopáusico mediante la evaluación de la hormona folículo estimulante (FSH)
