Implant Dentistry

Dominik Gross, Karin Gross, Mathias Schmidt
Dental implantology is one of the most attractive and dynamic fields of work within clinical dentistry. It provides many patients with new and improved opportunities for stable (implant-supported) rehabilitation and also offers dentists a field that is interesting in both technical and economic terms. Adverse clinical outcomes are, however, often the subject of discussion. These relate both to prosthetic failure and to biologic complications and side effects, namely persistent infections surrounding implants...

Osseointegrated implants have been recognized as being very reliable and having long term predictability. However, host-defense mechanisms against infection have been known to be impaired around a dental implant because of the lack of a periodontal ligament (PDL). The purpose of our experimental design was to produce cementum and PDL on the implant surface adopting cell sheet technology. To this aim we used PDL-derived cells, which contain multi-potential stem cells, as the cell source and we cultured them on an implant material constituted of commercially pure titanium treated with acid etching, blasting, and a calcium phosphate (CaP) coating to improve cell attachment...

When planned and implemented appropriately, single-unit implant dentistry in the smile zone can be an excellent alternative to attempting to save a failing natural tooth. Historically, implant success has revolved around assessment of osseointegration and the healing of bone around the implant, without much regard for esthetics upon completion. As implant dentistry has evolved, the expectations of both restoring clinicians and patients have expanded to emphasize the esthetic outcome as well as faster treatment with immediate implant placement...

Criteria for successful implants, in the rehabilitation of a single missing tooth in the esthetic area, should be determined by composite outcomes, including functional and esthetic aspects of soft tissues and the reconstruction, as well as patient-reported outcomes. This paper focuses on current methods in esthetic assessment and patient-centered/reported outcomes in single-tooth implant rehabilitation in the esthetic area. The relationship between subjective, patient-based esthetic evaluations and objective, professional-based esthetic evaluations is reviewed...

The reconstruction of deficient alveolar ridges using vertical and/or horizontal guided bone regeneration techniques allows for ideal implant placement, which is crucial for function and also for esthetically successful outcomes. Unlike in the past, when meeting a patient's functional demands was sufficient, many patients now have greater expectations from their implant restoration. Hence, it is no longer enough simply to restore the edentulous space with a functioning tooth or teeth. It has been suggested that patients now measure their final restoration using the contralateral natural tooth as the gold standard...

The rehabilitation of partially or totally edentulous patients with implant-supported prostheses has become routine, with excellent long-term outcome. A proper implant position is mandatory to achieve good functional and esthetic outcome and may require an adequate amount of alveolar bone and surrounding soft tissue. When this is lacking because of atrophy, sequelae of periodontal disease, traumas or congenital malformations, increased bone volume and/or keratinized mucosa can be obtained by guided bone regeneration, bone-grafting techniques and alveolar bone expansion...

Augmentation reality technology offers virtual information in addition to that of the real environment and thus opens new possibilities in various fields. The medical applications of augmentation reality are generally concentrated on surgery types, including neurosurgery, laparoscopic surgery and plastic surgery. Augmentation reality technology is also widely used in medical education and training. In dentistry, oral and maxillofacial surgery is the primary area of use, where dental implant placement and orthognathic surgery are the most frequent applications...

Implant dentistry has become a popular restorative option in clinical practice. Titanium and titanium alloys are the gold standard for endo-osseus dental implants production, thanks to their biocompatibility, resistance to corrosion and mechanical properties. The characteristics of the titanium implant surface seem to be particularly relevant in the early phase of osseointegration. Furthermore, the microstructure of implant surface can largely influence the bone remodelling at the level of the bone-implant surface...

Implant dentistry has become one of the most successful techniques for oral rehabilitation over the last 20 years. The success rate of implant oral rehabilitation is above 80% while peri-implant disease (PID) is the most important complication of implant dentistry. The main cause of PID is considered bacterial leakage at the implant-abutment connection of a two-piece implant system. Prevention and control of bacterial leakage at the implant-abutment connection is mandatory for reducing inflammation process around implants neck and achieving bone stability...

Photobiomodulation (PBM) is a non-invasive treatment that uses laser or led devices making its effects a response to light and not to heat. The possibility of accelerating dental implant osteointegration and orthodontic movements and the need to treat refractory bone lesions, such as bisphosphonate related osteonecrosis of the jaws, has led researchers to consider the effects of PBM on bone for dentistry purposes. The aim of our study was to investigate the effects of 915 nm light supplied with a GaAs diode laser on human osteoblasts in vitro...

Thymosin β4 (Tβ4) is known to inhibit an inflammatory response and to increase the survival of osteoblasts on titanium (Ti) surfaces. Ti is the most widely used graft material in dentistry; however, an inflammatory response induced following implant placement results in the generation of reactive oxygen species (ROS). The oxidative stress from the production of ROS such as nitric oxide (NO) and hydrogen peroxide (H2O2) can damage surrounding cells, resulting in implant failure by decreasing cell viability...

Increased life expectancy and broader restorative dental treatment alternatives for missing teeth have resulted in an increasing request of bone regeneration/augmentation procedures not only in healthy patients, but also in elderly and medically compromised ones. This is also combined with a growing demand for short implant loading protocols and for optimal aesthetic results. In order to meet these new dental needs, personalized treatment strategies tailored on each individual's characteristics and healing profile are warranted...

Insufficient bone volume is one of the major challenges encountered by dentists after dental implant placement. This study aimed to evaluate the efficacy of a customized three-dimensional polycaprolactone (3D PCL) scaffold implant fabricated with a 3D bio-printing system to facilitate rapid alveolar bone regeneration. Saddle-type bone defects were surgically created on the healed site after extracting premolars from the mandibles of four beagle dogs. The defects were radiologically examined using computed tomography for designing a customized 3D PCL scaffold block to fit the defect site...

BACKGROUND: Platelet-rich fibrin (PRF) has been applied in the clinical field for more than a decade, but largely in oral surgery and implant dentistry. Its utilization in plastic and reconstructive surgery is limited and lacking a comprehensive review. Hence, this article focuses on the various clinical applications of PRF pertaining to the plastic and reconstructive field through a systematic review. METHODS: In this review, articles describing the clinical application of PRF in plastic and reconstructive surgery were screened using predetermined inclusion and exclusion criteria...

Achieving successful long-term esthetic outcomes in implant dentistry requires that the height and width of the facial or buccal alveolar bone wall and, subsequently, the peri-implant tissues be maintained. Partial extraction therapy (PET) can be used to reduce the risk of facio-lingual collapse after tooth loss and improve the preservation of alveolar bone height and blood supply. This article demonstrates the use of PET for treatment of a hopeless tooth in the esthetic zone. After removal of the fractured maxillary central incisor, an implant was placed and restored with excellent esthetic, functional, and periodontal results...
