Low Level Laser (LED) Use to Increase Dental Implant Stability and Post Operative Analgesia

ImplantAnalgesia

Study hypothesis: Low level laser (LED) will reduce initial bone resorption and improve primary stability of dental implant. It will also reduces post operative pain compared to patient without treatment Implant osseointegration depends on many factors including biocompatibility of implant materials, design, surface, surgical access, patient conditions, biomechanical status, and lack of primary stability. Several in vivo and in vitro studies showed the healing effect of low level laser therapy (LLLT) on bone by decreasing the initial bone resorption postoperatively and increasing the primary stability of the implant. It has also shown to have an analgesic effect intraorally when used post intraoral surgical procedures. The exact mechanism is unclear despite the fact that many hypothesis has been proposed. In our study, our goal is to present, in a randomized standardized clinical trial, the effect of LLLT on post operative implant stability assessed by resonance frequency analysis (RFA). We will assess the subjective measures of postoperative pain using visual analog scale (VAS).

Standard Implants With Bone Regeneration vs Short Implants

Implant ComplicationBone Resorption

A study designed as a randomized controlled trial of parallel group design will be conducted at the Dental clinic of the University of Valencia to compare, considering different parameters, the rehabilitation with dental implants of atrophic posterior mandibles or maxillae using short implants or longer implants with vertical bone regeneration with GBR. The hypothesis of the study is that both treatment options will be successful to rehabilitate atrophic posterior mandibles or maxillae. Moreover, more surgical complications will be encountered in the bone regeneration group.

Autogenous Bone Mixed With Xenograft Versus Xenograft Alone Versus Absorbent Gelatin Sponge

Bone ResorptionAlveolar Bone Loss2 more

Alveolar bone atrophy post-extraction has been well documented in the past years. normal healing event results in a minimal loss of vertical height (around 1 mm), but a substantial loss of width in the buccal-lingual plane (4-6 mm). Alveolar socket preservation is thought to deal with this issue as to prevent the loss of alveolar bone dimensions post extraction in the case of delayed implant placement

Low Speed Drilling Versus Conventional Drilling Technique on Crestal Bone Level in Maxilla.(Group...

Bone Resorption

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.

Hyaluronic Acid Effect on Xenogenic Bone Healing

Bone ResorptionTooth Loss

The aim of this study is to test the hyaluronic acid hydrogel impact on the healing acceleration of xenogenic bone substitutes used in ridge preservation. Following tooth extraction, bone particles are mixed with the hyaluronic acid gel and grafted in the tooth socket. at the implant placement phase, a cone beam computer assisted tomography file is recorded in order to compare it with the baseline and a biopsy to evaluate the histological consequences.

Biomaterial Clinical Performance in a Socket Preservation Model

Bone LossAlveolar Bone Resorption

When a dental extraction is performed, sequential cascade of events happens that lead to a modeling and remodeling of the area. This phenomenon leads to bone resorption and consequential volume loss atrophy. In literature several biomaterials (Autogenous, alloplastic, allografts and xenografts) were tested as alveolar fillers with the aim of controlling this physiologic event. Socket preservation is today a very widely spread dental technic to preserve the alveolar dimensions, that uses a wide range of biomaterials. Alloplastic materials have a fair evidence to work in several regenerative procedures in the oral and maxillofacial region. This pilot trial aims to characterize Histologic bone healing pattern in a human socket preservation model of 2/3 biphasic calcium sulfate cement matrix's and Hydroxyapatite (HA granules). Alterations in Volumetric alveolar socket changes in a socket preservation clinical model will also be studied.
