Comparison of intra-articular injection of plasma rich in growth factors versus hyaluronic acid following arthroscopy in the treatment of temporomandibular dysfunction: A randomised prospective study.

Purpose: The main objective of our study was to evaluate the effectiveness of the injection of plasma rich in platelet-derived growth factors (PRGF) versus hyaluronic acid (HA) following arthroscopic surgery in patients diagnosed with internal derangement of the temporomandibular joint (TMJ) with osteoarthritis (OA).

Materials And Methods: A total of 100 patients were randomised into two study groups. Group A (n = 50) received an injection of PRGF, and Group B (n = 50) received an injection of HA.

Complications of temporomandibular joint arthroscopy using two-portal coblation technologies: A prospective study of 475 procedures.

Purpose: To study the complications of temporomandibular joint (TMJ) arthroscopic procedures using two-portal coblation technologies.

Materials And Methods: The 397 consecutive patients (475 joints) who underwent arthroscopic surgery were prospectively analyzed.

Results: Complications were observed in 39 (8.

Subnasal modified Le Fort I osteotomy: indications and results.

Purpose: To study the possible morphologic changes in the nose after subnasal modified Le Fort I maxillary osteotomy to correct class III dentofacial deformities in patients with considered normal nasal morphology.

Material And Methods: Fifteen patients (7 males, 8 females) requiring maxillary advancement to treat class III dentofacial deformities were studied prospectively between January 2004 and January 2011. All the patients had an adequate projection of the nasal tip preoperatively preventing a conventional Le Fort I osteotomy.

Prosthodontic rehabilitation in patient with ectodermal dysplasia combining preprosthetic techniques: a case report.

Oral manifestations in ectodermal dysplasia include oligodontia, alveolar ridges hypoplasia, and others. Due to the special conditions in terms of unhealthy teeth and lack of bone, implant-supported rehabilitation seems to offer the most satisfactory outcome. A 27-year-old male diagnosed with ectodermal dysplasia was referred to our department for oral rehabilitation.

A sheep model for endoscopic treatment of mandible subcondylar fractures.

Background: Mandible subcondylar fractures may be treated via a traditional visible access incision; however, with the advances in surgical endoscopy surgeons are transitioning to a minimally invasive approach in an effort to reduce surgical morbidity and external facial scarring. We sought to design a clinically applicable teaching tool in a large animal model that would allow the operator to gain experience treating mandible subcondylar fractures via an endoscopic approach.

Methods: A large animal model was developed using the Churra sheep.

Efficacy and safety comparison of two amoxicillin administration schedules after third molar removal. A randomized, double-blind and controlled clinical trial.

Objective: The aim of this comparative double-blind, prospective, randomized, clinical trial was to evaluate two amoxicillin administration patterns. The first was a short prophylactic therapy and the second a long postoperative regimen.

Study Design: The study population consisted of 160 patients who underwent mandibular third molar extraction.

A comparative study of platelet-rich plasma, hydroxyapatite, demineralized bone matrix and autologous bone to promote bone regeneration after mandibular impacted third molar extraction.

Objectives: 1) to compare mandibular bone regeneration by applying autologous bone, platelet-rich plasma and two biomaterials (synthetic calcium hydroxyapatite, and demineralized bone matrix), and thus establish the potential benefits of these biomaterials in the regeneration of postextraction alveolar bone, 2) to identify which of them accelerates more bone regeneration and 3) to determine whether there are differences in the postoperative period (pain, swelling, trismus, infection) depending on the material used.

Study Design: It consists in a prospective, controlled (with a split- mouth design) and double blinded study. We use as a model an easily reproducible non-critical bone defect: the defect that remains after extraction of mandibular impacted third molar.

Is PRP useful in alveolar cleft reconstruction? Platelet-rich plasma in secondary alveoloplasty.

Objective: Cleft lip and palate is a congenital facial malformation with an established treatment protocol. Mixed dentition period is the best moment for correct maxillary bone defect with an alveoloplasty. The aim of this surgical procedure is to facilitate dental eruption, re-establish maxillary arch, close any oro-nasal communication, give support to nasal ala, and in some cases allow dental rehabilitation with osteointegrated implants.
