Combined novel approaches to the microscopic study of the dental implant site

We studied trephine core samples taken from 252 sites where implants were to be placed in a series of 35 patients; all material was obtained with patient consent and local ethical committee approval. The sites were both native cores where implants were placed at the first operation and grafted sites, where a sinus lift procedure had been performed approximately six months before the second operation to place the implant. Samples were embedded in PMMA and blocks were finished to produce polished longitudinal sections through the cores which were studied by (a) quantitative backscattered electron (BSE) SEM; (b) X-ray microtomography (XMT) using the QMUL MuCAT scanner to make direct correlations between the current block face imaged with qBSE SEM and rendered XMT data; and (c) after iodine staining for BSE SEM to read soft tissue and cellular histology. The combination of methods gives important new information.

Simultaneous implant placement in sinus grafted sites and loading at six weeks

Over the past two years at my practice we have integrated a system of simultaneous sinus grafting and implant placement allowing us to restore many implants following six weeks of healing. Conventionally, healing in sinus grafted sites has taken a considerable period of time and people have assessed sinus grafting sites on residual alveolar height alone. During this presentation I hope to demonstrate that residual height is less significant in the ability to achieve primary stability, and measuring this during simultaneous implant placement will increase the scope to place more implants earlier and to restore even earlier again. The common pathway in my practice for sinus grafted situations is simultaneous placement and loading at six weeks. I will demonstrate a significant audit of hundreds of implants in hundreds of sinus grafts and the practical aspects of providing this treatment.

Implant maintenance and note keeping - current protocols and quality assurance

This audit project formed part of my MSc for Warwick Implant course. Current national guidance on implant maintenance appointments and the criteria by which we should be assessing the health of implants/implant patients are highlighted. A literature search revealed the evidence behind this national guidance and I then created a template to use to audit my own clinical notes in primary care. The audit of clinical records looks at notes from around two hundred maintenance appointments of patients who had previously received dental implants and shows some shocking results - we are poor at assessing ALL the criteria we should at each appointment and the criteria assessed can be inconsistent even by the same clinician at different appointments. A maintenance protocol note template is created and then a prospective second cycle audit completed showing great improvement in record keeping. ADI members will benefit from understanding the guidance and considering self-audit.

Aesthetic results of dental implants in the maxillary anterior zone can be optimised using the Labial Glove and the subepithelial connective graft

Tooth extraction causes resorption of the alveolar buccal wall/socket, in both maxilla and mandible. Loss of the buccal wall degrades the visual aesthetics of the prosthetic rehabilitation. Additionally, the harmony of hard and soft tissue morphology can be impaired during surgery. Tissue augmentation can be carried out consecutively with an extraction/immediate implant placement or following bony resorption in the delayed scenario. The subepithelial connective graft (SCTG) is used to mask inadequate tissue volume and suboptimal aesthetic morphology. I have described the predictable fixation of the SCTG to implant sites ensuring the non-extrusion of the graft. Now, one needs to address the demand of the extreme high profile site: the anterior maxilla, producing the invisible result. For this, I have developed the Labial Glove Flap with fixed Underlay Graft of the SCTG. This ‘step-by-step’ presentation is illustrated by (at least) 20 cases with follow-ups ranging from 12 - 72 months.

Plasma and balloons

The recapture of both soft and hard tissue loss can be corrected to varying degrees with various methods. The resulting morbidity can often be significant for our patients. Thus the scope of this presentation is to demonstrate the use of osmotic tissue expanders (balloons) to facilitate repair of tissue defects, and to show how plasma rich in growth factors can be of benefit in differing conditions. Both of these applications reduce patient morbidity in the more challenging cases. This paper will present: (1) a brief literature review of balloons; (2) a brief literature review of plasma rich in growth factors; (3) clinical case examples of the use of both balloons and growth factors; (4) a case report involving reconstruction of part of a mandible using a combination of techniques to achieve a functional outcome. There will also be some commentary about the speaker's experience with balloons and their complications.

Oxygen therapy for the treatment of peri-implantitis

Peri-implantitis and periodontitis are bacterial infections with chronic inflammation characteristics. The pO2 value in areas of peri-implantitis is significantly lower than in healthy tissue. Moreover, pO2 value correlates with pocket depth; the deeper the pocket, the lower the pO2 value. These lower oxygen levels reduce the body’s resistance to bacteria and healing potential. Wound healing requires a variety of cells to increase their metabolic activity and this results in a high oxygen demand. Oxygen at the wound site has been shown to promote wound healing. Often, local or systemic antimicrobials are used to support peri-implantitis treatment. These products are known to have beneficial effects, but also have limitations, disadvantages and side effects. We have been using a protocol to apply topical active oxygen therapy in peri-implantitis cases. The results are showing some promise in the successful treatment of peri-implantitis cases.

Do lasers present a useful tool to assist the management of peri-implant disease?

Overload? Foreign body reaction?, or infection? How does one treat a disease where there is so much confusion and speculation on aetiology? Confusingly, the literature describes a “scatter gun” approach to treatment from antibiotics, to ultrasonic debridement, with and without polymer coated tips, to blasting implant surfaces with powders, to scrubbing the implant surface with NiTi brushes, to implantoplasty, all with non-surgical and surgical approaches, sometimes with combination therapies. Given that recent studies suggest that prevalence of peri-implant disease may be as high as 50%, and consumer trend reports predict a rapid rise in uptake of implants, the UK is braced with a burgeoning epidemic of peri-implantitis. With this in mind, implant practitioners need to consider the prospect of treating this disease themselves. This presentation considers the emerging evidence in the use of lasers to assist management of peri-implant infection.

The conometric technique – the answer to our full-arch implant bridge problems?

The fact that there are so many different ways of treating full-arches with implants is testament to the fact that there is no one best way of doing so, each method having its pros and cons. Even that best way of attaching the full-arch bridge to the implants is debated, with some wanting to cement their bridges and others preferring them to be screw-retained. In this talk the conometric technique will be presented, which allows a full-arch implant bridge of any material to be securely attached to the implants without the need for screws or cement. It has the advantages of each technique and the disadvantages of neither. I have cemented a reasonable number of full-arch implant bridges. I have screw-retained well over 70 full-arch implant bridges. Now the full-arch implant bridges that I do are all conometric.

Fixed full arch restoration – is there an easy and lasting solution?

The challenge of full arch restoration has been the aesthetic and functional rehabilitation, which is often compromised by post-extraction resorption. This talk briefly compares and contrasts the approaches to fixed full arch restorations and looks at how technological developments with implant prosthetic component design can allow for a potentially simpler more cost effective solution for full arch fixed restorations in conjunction with CAD milled superstructures.

Full arch all zirconia and ceramic bridgework - can we finally move past acrylic and titanium?

For over 30 years the standard to replace all the teeth in an arch has been the hybrid bridge, originally cast gold and acrylic and more recently titanium and acrylic. Despite advances in denture teeth and acrylics, problems continue to occur with debonding of teeth, discolouration and fracture of acrylic being frequent. Implant companies have built their own CAD/CAM milling facilities and many third party milling facilities are appearing, offering a wide variety of solutions from milled cobalt chrome to one piece all zirconia bridges. This presentation looks at the advances in the production of one piece screw retained frameworks and will provide practical advice based on the experience we have gained using, almost exclusively, all-zirconia and ceramic based frameworks for the last 5 years.
