The aims of the present case report are to describe non-surgical management in addition hyaluronic acid application two gingival recessions with cleft and perform a narrative review on newest evidence treatment recessions. A 47-year-old female patient dentine hypersensitivity pain during brushing has type 1 recession red Stillman's 1.4 1.5. defects have been treated Gracey curette n° 7/8 cause bleeding. Sodium hyaluronate gel applied sulcus both elements affected. Three months after tissue...

Abstract Background Fully adjustable articulators and pantographs record reproduce individual mandibular movements. Although these instruments are accurate, they operator-dependant time-consuming. Pantographic recording is affected by inter intra operator variability in the individuation of clinical reference points afterwards reading pantographic themselves. Finally only border movements can be reproduced. Methods Bionic Jaw Motion system based on two components: a jaw movement analyzer...

The purpose of this in vitro study was to evaluate the external marginal gap variation with a 3D quantitative method and residual fracture resistance after cyclic fatigue endodontically treated molars restored overlays different materials, without fiber posts-supported buildups. Forty-eight human maxillary were selected, treated, prepared standardized MOD cavities randomly allocated into 6 groups considering “core strategy” (build-up composite resin; build-up resin supported by post);...

The aim of the present study was to investigate accuracy a new digital impression system, comparing it plaster technique in realization full-arch implant-supported metal frameworks.We took 11 scans (8 upper maxilla and 3 lower jaw) on sample nine patients previously rehabilitated with fixed screw-retained prostheses following Columbus Bridge Protocol (CBP) four six implants (total: 51) since at least 4 months. Two impressions were taken for each dental arch: one analogic using pick-up...

The present article aims to describe the management of a malpractice dental implant case in patient with history oral bisphosphonates (BF) intake (alendronic acid every 15 days for 20 years) and perform narrative review recently published articles (2019–2023) on topic. A female rehabilitated 18 nails mandible years ago underwent two surgeries; first one included explantation nails; second insertion implants anterior region. At last follow-up (21 months from surgery one) no complications nor...
