OBJECTIVE: The mere osseointegration of an implant should no longer be considered a satisfactory criterion for success. Tooth extraction itself and, more importantly, possible local comorbidities such as periodontal or endodontic diseases, cause a reduction in the gingival volume of the edentulous site due to bone atrophy. This reduced volume must be treated and resolved to obtain a satisfactory esthetic result, which is an essential factor for successful implant rehabilitation. The classic approach to this problem relies on bone augmentation procedures...

Ihsène Taihi, Loredana Radoi
Chronic non-suppurative osteomyelitis (CNSO) is a chronic bone disease and may be associated with a reparative periosteum entity called proliferative periostitis (PP). This condition rarely affects the maxillofacial region. Mandibular cases were already described for an infectious dental cause, often with an "onion skin" radiographic aspect, but some rare reported cases showed no obvious etiology. They represent a challenge for diagnosis because of possible misdiagnosis leading to unsuccessful or inappropriate treatment attempts...

OBJECTIVE: Bone and soft tissue calcifications can often be visualized on panoramic radiographs, thus leading to presumptive diagnoses requiring further examinations. This cross-sectional study determined the prevalence of suspected carotid artery calcifications, tonsilloliths, calcified submandibular lymph nodes, sialoliths of the submandibular glands, and idiopathic osteosclerosis in a Lower Austrian subpopulation. METHOD AND MATERIALS: Digital panoramic radiographs (DPR) taken from 1,042 subjects for other clinical purposes between the years 2013 and 2015 were evaluated, using a standardized template...

OBJECTIVE: The gingival tissues surrounding the maxillary anterior teeth play a pivotal role in fostering a beautiful smile. The gingival zenith position (GZP) and its spatial orientation in the mesiodistal and apicocoronal direction can provide a valuable reference point. The present study was undertaken to evaluate the GZP and gingival zenith line (GZL) in maxillary anterior teeth in different age groups and genders. METHOD AND MATERIALS: The study population comprised 124 periodontally healthy patients equally divided into 21 to 40 years (Group I) and 41 to 60 years (Group II) age groups and gender distribution...

The concept and application of a temporomandibular joint (TMJ) relationship identified as centric relation (CR) has changed significantly over the past century. Originally proposed as a biologically reasonable position where maxillary and mandibular dentures should occlude, it later was applied to the dentate population as well. The term "ideal" was used by the gnathologic dental community as they sought to define the exact details of CR in terms of condyle-fossa relationships. Assessments of patients' occlusion were then made in relation to CR, and discrepancies between the two positions were described as being problematic...

OBJECTIVES: An implant with an acid-etched fixture surface and internal-hex collar may achieve greater osseointegration. The goal of this research was to study the effects on long-term bone healing of fixture surface acid-etching and machined collar design. METHOD AND MATERIALS: Three two-part implant types were compared: standard Brånemark (with an external-hex 1.2 mm long machined flat collar), Swede-Vent (a copy of the Brånemark design, with an identical collar but a fixture surface acid-etched to 1 to 3 µm), and Screw-Vent (with a fixture surface acid-etched identically to that of Swede-Vent, but a longer internal-hex machined flat collar that did not require countersinking)...

The purpose of this topic review is to give a general overview of gingival retraction agents used during prosthodontic treatment, and the possible difficulties connected to them that may be faced by the dentist. Hemostatic agents are important for successful gingival retraction and in achieving hemostasis. However, these agents may show numerous negative effects on the prosthodontic treatment and oral tissues of which the practicing dentist must be aware, and which will be elucidated in this review. PubMed and Google Scholar databases were searched for publications up to and including 2017...

OBJECTIVE: Removal of third molars (3Ms) is one of the most common surgical procedures performed by dental surgeons. 3Ms that are associated with pathologic changes such as infection, nonrestorable caries lesions, cysts, tumors, and destruction of adjacent teeth and bone are under consensus for their removal. However, debate exists regarding the prophylactic removal of asymptomatic impacted 3Ms. This review attempts to establish indications for prophylactic extraction of 3Ms. METHOD AND MATERIALS: Clinical experience and a summary of the literature are presented concerning the effects of retained 3Ms in relation to caries and periodontal disease, dental arch changes and anterior crowding, cysts and other etiologies, mandibular fractures, temporomandibular pain, and aging of bone...

OBJECTIVE: Surgical time prediction is an important factor to plan both clinical and organizational aspects of mandibular impacted third molar extraction. Many classifications have been proposed over the years, but their accuracy in surgical time prediction remained questionable. The present study introduced a modification of Juodzbalys and Daugela (JD) classification, and had the aim to validate its effectiveness in predicting the duration of the surgery. METHOD AND MATERIALS: Three centers treated patients needing impacted mandibular third molar extraction, following inclusion and exclusion criteria...
