Software applied to oral implantology : update
Software in combination with imaging techniques is used increasingly for diagnosis, planning and treatment in oral implantology. Computer-aided surgery allows a great accuracy in implant positioning to be obtained, taking advantage of the amount of bone available and facilitating minimally invasive surgery. It is a significant aid in determining implant number, location, angle and characteristics. A CT with a radiographic template positioned in the mouth is made for the patient. Data are stored on a CD in DICOM 3 format and then introduced in the computer where implant treatment will be planned, using the chosen software. Navigation improves surgical accuracy through the aid of software bas…
Oral rehabilitation with dental implants in patients with recessive dystrophic epidermolysis bullosa : a retrospective study with 2-15 years of follow-up
Background Epidermolysis bullosa (EB) comprises a group of hereditary disorders characterized by mechanical fragility of the skin and mucous membranes, with the development of blisters and vesicles in response to minimum tissue friction. Recessive dystrophic epidermolysis bullosa (RDEB) with generalized involvement is the most common subtype in the oral cavity. The present study was carried out to investigate dental implant survival, peri-implant tissue condition, patient satisfaction, and the impact of treatment upon the quality of life of patients with RDEB rehabilitated with implants and full-arch implant-supported prostheses. Material and Methods Thirteen patients with RDEB underwent de…
Ultrastructural study by backscattered electron imaging and elemental microanalysis of biomaterial-to-bone interface and mineral degradation of bovine xenografts in maxillary sinus floor elevation.
Objectives The aim of this study was to perform an ultrastructural study of the bone-to-biomaterial interface and biomaterial mineral degradation in retrieved bone biopsies following maxillary sinus augmentation using bovine xenografts (Endobon®) in 15 clinical cases.

Oral mucocele: review of the literature
Mucocele is a common lesion of the oral mucosa that results from an alteration of minor salivary glands due to a mucous accumulation. Mucocele involves mucin accumulation causing limited swelling. Two histological types exist - extravasation and retention. Mucoceles can appear at any site of the oral mucosa where minor salivary glands are present. Diagnosis is principally clinical; therefore, the anamnesis should be carried out correctly, looking for previous trauma. The most common location of the extravasation mucocele is the lower lip, while retention mu- coceles can be found at any other site. Mucoceles can affect the general population, but most commonly young patients (20-30 years old…

Vestibular bone window for the extraction of impacted lower third molars : four case reports
Four patients attending for the extraction of an impacted lower third molar are reported. The aim of this paper is was to describe a technical approach, which facilitates impacted lower third molar extraction, minimizing the ostectomy, thus reducing secondary postoperative manifestations and avoiding possible periodontal defects on the distal side of the second mandibular molar. To facilitate the extraction of the crown, roots or the complete molar, a small ostectomy in the form of a window can be made in the vestibular cortical, approaching the extraction through the resultant mesial space.

Subcutaneous emphysema resulting from surgical extraction without elevation of a mucoperiosteal skin flap
Subcutaneous emphysema, is a rare occurrence in dental practice. It is usually benign and self-limiting; nevertheless, severe consequences can result from surgical treatment. Emphysema occurs when air is injected into the subcutaneous layer of the tissue, this may come from either an air turbine handpiece or air syringe. Due to the danger of developing emphysema, procedures using compressed air are not recommended in dental extractions involving the raising of a skin flap, bone sectioning or exeresis. Two determining factors are always involved with subcutaneous emphysema. On the one hand, a compressed air procedure (air turbine handpiece, air-water syringe), and on the other, a communicati…
