Filter by:The healing process after tooth removal involves bone remodelling which implies some loss of alveolar bone volume.Among materials proposed for minimising this remodelling and preserving the bone, autologous dental tissue is a promising option, but more data are needed. In this context, the investigator evaluated size and density changes using cone beam computed tomography in autologous dental material (ADM)-preserved sockets compared to controls,and assessed biological responses by histological analysis of bone implant contact (BIC) an Area density (AA) using experimental Bioetch® surface implant.
A single-centre randomised controlled pilot study involving 12-24 healthy adult patients for investigating dental extraction socket healing with and without plasma rich in growth factors (PRGF) taking place during early days of healing (days 1, 3, 7, 15, 30) and relating the healing to clinical and histological outcomes after 90 days of healing. Healing will be investigated by means of various non-invasive imaging technologies (e.g. laser scanners, thermal cameras, laser cameras) in addition to conventional technologies (e.g. bone core biopsy, 3D xray images). At 90 days of healing, dental implants will be placed in the healed sockets and implants will be restored and followed up until 12 months after connecting the prosthesis to the implant (e.g. implant crown). Dental implant outcomes (e.g. survival, success) will also be evaluated.
The aim of this pilot study was to assess survival rates and peri-implant bone loss of two narrow-diameter titanium-zirconium implants supporting maxillary and mandibular overdentures during an observation time of 3 years. The masticatory performance, self-reported chewing ability and change of oral health impact profile (OHIP) after rehabilitation were also investigated.
20 patients were selected requiring implant placement and divided randomly into two groups (10 in each group) - for the study group, starter drill is used to locate the point of insertion as planned then pilot drill is also used to the full desired working length after that all other sequential drills are used at a low speed (50-70 rpm) without irrigation . - In the study group: implant will be inserted in the low speed osteotomy site. • In the control group: implants will be inserted in the conventional prepared osteotomy site. - For both groups there is no surgical guide used. - The flap will then be copiously irrigated with saline in preparation for closure. - The flap will then be closed using interrupted 4/0 resorbable sutures.

This is a two-year prospective randomized clinical study to to evaluate whether the gingival thickness and insertion depth of dental implants have any influence on marginal bone levels changes around platform switched implants.
This is a controlled, randomized, intervention trial (CRIT) with 20-40 year old overweight individuals (n = 320) across Europe in order to distinguish between biologically active components of seafood, i.e., seafood proteins and n-3 lipids, regarding their effects on risk factors for metabolic syndrome, bone health, and weight management.
