Izidoroa, J. Lobatoa, M. Vilhenaa, M. Nemesioa, L. Proençab, J. Mendesb and R. Alvesa,baPeriodontology Department, Clinical Research Unit (CRU), Egas Moniz Cooperativa de Ensino Superior, Caparica, Portugal; bCentrode Investigação Interdisciplinar Egas Moniz (CiiEM), Egas Moniz Cooperativa de Ensino Superior, Caparica, PortugalABSTRACTIntroduction: One of the main goals of periodontal treatment is the regeneration of lost tissues, in order to improve theprognosis of the involved teeth [1–3]. Guided tissue regeneration (GTR) involves the use of a barrier with or without theuse of bone substitutes [4]. Given the great diversity and constant evolution of materials, it is necessary to maintain apermanent evaluation of their clinical effectiveness. This study intends to evaluate the success and predictability of GTRusing a new membrane and bone substitute of equine origin (HeartVR and Mix GranulesVR – Bioteck SpA, Turin, Italy), inthe treatment of infra-bony defects with two or three walls [5].Materials and methods: This study was approved by Egas Moniz Ethics Committee and all patients signed an informedconsent form. Patients were selected among those referred to the Department of Periodontology/EMDC, with indicationfor surgical periodontal treatment, presence of 2–3-wall infra-bony defects, probing depth (PD) 	 5mm, infra-bony com-ponent 	4mm deep (evaluated radiographically) and attached gingiva 	2mm. Exclusion criteria were: cases with PIaqueIndex (PI) >20%, smokers, extension of the defect to the furcation zone, mobility grade III, endodontic pathology, dia-betes or other pathologies that interfere with bone remodelling and metabolism or contraindicate periodontal surgery.All surgeries were performed by the same operator. The clinicians involved in the evaluation of the results had no inter-vention in surgery. The following clinical and radiographic parameters were evaluated at one, three and six months aftersurgery: PI, Gingival Index (GI), Probing pocket depth (PPD), Bleeding on Probing (BoP); Gingival recession (GR), height ofkeratinised gingiva (KG) and radiographic angle of the defect (RAD). In addition, the presence of possible intra-surgical orpost-operative complications was also evaluated. The assessment of the defect depth reduction was based on standar-dised periapical radiographs obtained through the use of an individualised device (parallelizer).Results: A total of six participants (83% females, 17% males), with a mean age of 61.6 (± 8.1) years, were enrolled in thestudy. The number of defect walls was: 3 walls (50%), 2 walls (33.3%) and 2/3 walls (16.7%). After six months, an averageclinical attachment level gain of 3.3 (± 1.4) mm, mean radiographic bone filling of 72 (± 29%) and a BoP reduction of66.6% were observed. RAD average was 21.3 (± 1.2) and GR changed from 2.2 to 2.7mm. Membrane exposure wasobserved in 33.3% of the cases, however, there were no cases of infection or severe pain.Discussion and conclusions: The use of collagen membranes and corticocancellous bone grafts of equine origin seemsto be a viable alternative in the regeneration of infra-bony periodontal defects.CONTACT C.

Rodriguesa, B. Saldanhab, P. Sottomayorb and R. VazbaImplantology Consultation at I.U.E.M.’s Dental Clinic, Egas Moniz CRL, Caparica, Portugal; bVoluntary Formation in the ImplantologyConsultation at I.U.E.M.’s Dental Clinic, Egas Moniz CRL, Caparica, PortugalABSTRACTIntroduction: In the anterolateral wall of the maxillary sinus, an osseous canal can be observed, corresponding to theanastomosis between arterial branches of the posterior superior alveolar artery and the infraorbitary artery [1]. From thisanastomosis, mostly known as Antral artery, its several branches allow for the vascularisation of the sinus mucous mem-brane, periosteum and the anterolateral bone wall of the sinus [2].Surgical approach of this region, including antrostomy for external sinus lift of the maxillary sinus, can result in intraoper-ative bleeding due to vascular lesion during the osteotomy [3]. Current radiological 3D modelling of the sinus anatomy,as well as solid knowledge of sinus anatomy are of the upmost importance to prevent vascular complications duringthese surgical procedures in this area.The objective of this presentation is to graphically review and demonstrate anatomical concepts on sinus anatomy, throughlive and interactive a viva voce anatomical black board and chalk schematic drawings, based on the general narrative descrip-tion of sinus anatomy, as well as anatomical findings regarding antral artery position in cadaveric studies [4–7].Materials and Methods: Medline (Pubmed) search using the following: “vascularization maxillary sinus cadavers”, com-pleted with the revision of the bibliographical references of the selected articles in order to identify further relevant stud-ies. Inclusion criteria: (1) Published between 2008 and 2015. (2) Cadaver Studies. (3) Studies that evaluate the position ofthe anatomical position of the anastomosis between arterial branches of the posterior superior alveolar artery and theinfraorbitary artery. Exclusion Criteria: (1) Non cadaveric studies. (2) Foetal and paediatric studies.Results: Eight articles were selected.Discussion and conclusions: The vascular anastomosis is frequently found in the lateral wall of the maxillary sinus. Itsposition and depth are variable, as well as its trajectory and morphology. Pre-surgical determination of its precise ana-tomical variations is of the utmost importance to avoid vascular damage and complications during external sinus liftsosteotomies.CONTACT P.
