Functionalization of scaffolds with NaOH-based solution can improve bone regeneration.

Multidisciplinary approach with bilateral sinus-lift and full-mouth implantology in patients with severe sinusitis.

Aim: To comparatively evaluate the outcomes of professionally administered plaque removal (PAPR) and photodynamic therapy (PDT) in the treatment for experimentally induced gingivitis (G) and peri-implant mucositis (p-iM). Materials and methods: Twenty systemically healthy patients, each contributing a single implant-supported unit in a posterior sextant and a tooth within the same quadrant, were selected. Patients underwent an experimental G and p-iM trial consisting of a 2-week period of undisturbed plaque accumulation and a 6-week resolution phase following treatment administration.

The purpose of this study was to evaluate the scientific literature related to the use of graphene and its derivatives in dentistry. Electronic research was carried out on PubMed, Scopus and Web of Science. The studies found included the following topics: the use of graphene in tissue engineering, implantology, as an antibacterial material and in the manufacture of dental materials.

Background: Prevalence of peri-implantitis is directly proportional to the time of
functional loading.
The aim of this retrospective study was to assess the survival and success rates as well
as the incidence of peri-implantitis among patients with a history of periodontitis and
among implants.
Material and Methods: We evaluated clinical records of periodontally compromised
patients treated between January 1998 and July 2002, with implants enrolled in a
supportive periodontal and peri-implant treatment (SPT) follow-up programme. The

BACKGROUND: The literature indicates that 0.5 to 1.5
mm of gingival recession most often occurs within the first
months after implant placement or abutment connection. The
aim of this study is to test the validity of the new Biotype
implant design (Vertical Neck®) to evaluate the effect of a
concave transmucosal profile on the vertical stability of soft
tissues at the facial aspect of dental implants, taking advantage
of the benefits deriving from intraoral digital impression.
METHODS: The study was carried out at the Department of

The surgical treatment of peri-implantitis is currently based on the removal of biofilms from the implant surface by primary means of mechanical and physical treatments. However, such approaches often determine some alterations of the implant surface with detrimental effects on re-osseointegration. This study aims to evaluate the effects of four different mechanical and physical treatments on titanium samples with moderately rough surface. Air powder abrasion (AP) with glycine powder, a titanium brush (TB) and a diode laser at 3 W (L3) and 4 W (L4) were tested.

The aim of this report was to describe a new computer-guided technique for a controlled site preparation and palatal orthodontic miniscrew insertion using a dedicated software. A surgical guide was designed after planning the appropriate insertion sites on three-dimensional images created by the fusion of cone-beam computed tomography (CBCT) and digital dental model images. Pre- and postoperative CBCT images were compared and the angular, coronal, and apical deviations between the planned and the placed miniscrews were calculated.
