Guided bone regeneration via a preformed titanium foil: clinical, histological and histomorphometric outcome of a case series.

Purpose: The aim of this paper was to evaluate the histological and histomorphometric outcome of Preformed Titanium Foil (PTF) to perform Guided Bone Regeneration (GBR) in posterior mandibular atrophies.

Materials And Methods: 10 subjects (1 male; 9 females; mean age 58±11.37 years), with distal mandibular atrophies were selected to perform GBR by means of PTF, using a moldable allograft paste as graft material.

Endoscopic management of the schneiderian membrane perforation during transcrestal sinus augmentation: a case report.

Purpose: In this article the Authors describe a procedure aimed to restore under endoscopic control, the continuity, of the Schneiderian membrane (SM) incidentally teared during a sinus lift with transcrestal approach.

Materials E Methods: In a 44-year-old male, due to aforementioned complication, the SM was gently detached via transcrestal approach, with a customized small ball burnisher, in order to facilitate the placement of a collagen sponge, to close the communication with the sinus, followed by the subsequent insertion of a graft material. All the procedure was endoscopically controlled and, considering the successful grafted area elevation, was simultaneously followed by implant placement.

Full arch rehabilitation in severe maxillary atrophy with palatal approach implant placement: a case report.

Purpose: The edentulous severely atrophic maxilla, as consequence of alveolar bone resorption and pneumatisation of the maxillary sinus, represents a serious limitation to the implant rehabilitation. Implants insertion via palatal approach (PA), in combination with relatively minimally invasive techniques aimed at increasing bone volume without the use of autologous bone harvesting is a valid alternative among the options for the rehabilitation of the upper jaw.

Clinical Case: In a 70-year-old female, with a severe maxillary atrophy, 6 spiral taper implants were placed with the PA, combined with the bilateral transcrestal elevation of both the sinus floors and nasal cavities; a further GBR, with resorbable pericardium membrane covering a termoplastic allograft associated to a xenograft, was performed.

Efficacy of a new implant-abutment connection to minimize microbial contamination: an study.

Purpose: The aim of the present study is to evaluate the effectiveness of Ditron implants abutment connection (IAC) to sealing the gap between two pieces.

Materials And Methods: To identify the efficacy of a new IAC, the passage of genetically modified bacteria across IAC was evaluated. A total of five Ditron Implants were used.

The use of various biomaterials in computer-guided crestal sinus lift procedures. A report on two case studies with volume comparison.

Purpose: In the context of the transcrestal maxillary sinus lift a wide variety of biomaterials have been used to fill the subantral space over the years. In this study, two types of biomaterials were used in order to fill the maxillary sinus: a nano-crystallized hydroxyapatite in an aqueous solution and a micronized heterologous bone in a collagen matrix.

Materials And Methods: The surgical procedures were designed and carried out using computer-guided surgery.

Endoscopic retrieval of a dental Implant into the maxillary sinus: a case report.

Purpose: In this article the Authors show a safe and predictable technique to remove displaced implants from the maxillary sinus.

Materials And Methods: A 49-year-old female was referred, to this centre by a general dentist, for the retrieval of the ectopic dental implant. After a preliminary clinical and radiological evaluation of the case the surgical procedure was performed.

Upper full arch rehabilitation with sinus by-pass with tilted implants via tapered-threaded expanders in low density bone: a clinical trial.

Purpose: In the present paper the use of tapered-screw bone expanders (TSBEs) is proposed, in combination with the placement of tilted implants, in close proximity to the anterior sinus wall, solving the problem of the reduced height of the alveolar bone in the sub-antral area. The Authors present a case series of full-arch rehabilitations performed with this procedure named: Tilted Implant Expansion Osteotomy (TIEO).

Materials And Methods: 12 patients (5 males and 7 females, average age 58.

Diffusion of light through quartz fiber-reinforced epoxy resin double taper posts.

Purpose: The aim of this study was to evaluate the progression of the light through a series of translucent posts available on the market (D.T. Light-post, R.

Observable deviation of the facial and anterior tooth midlines.

Statement Of Problem: It has been recommended that the anterior tooth midline be placed coincidently with the midline of the face (facial midline). The location of the facial midline depends largely on the judgment of the clinician. The amount of deviation between these 2 midlines that is noticeable to the observer has not been fully investigated.
