Horizontal lack of residual ridge width can complicate the implant procedures. Therefore, ridge construction prior to implant placement is a biomechanical requirement. Guided bone regeneration, bone grafting, alveolar ridge splitting and combinations of these techniques are used for the lateral augmentation of the alveolar ridge. The ridge splitting technique with simultaneous implant placement seems to be a minimally invasive treatment option for horizontal augmentation of narrow alveolar ridges with adequate vertical height. This paper thoroughly describes a segmental ridge splitting technique with both vertical and horizontal osteotomy cuts followed by the use of chisel and mallet to lateralise the buccal bone which was accompanied by GBR and simultaneous implant placement.

The aim of this research was too compare the thickness change of labial contour and bone tissues, as well as some biological complications of immediate implantation with and without immediate provisionalization for a single anterior maxilla presenting a vertical defect on labial bone with the need of guided bone regeneration (GBR) by a flap approach. A total of 40 single implants were placed in 40 patients into fresh extraction sockets of the anterior maxilla with a vertical defect on the labial bone (<4 mm). Simultaneously, GBR was conducted at the sites by a flap approach, and the implants were given immediate or delayed provisionalization. The thickness change of bone tissues during six-month evaluation and labial contour during three and six-month follow-up were measured. Complications such as implant and restoration survival rates, infection as well as wound exposure were also evaluated at six months postoperatively. After six months, the mean thickness losses in labial bone were 0.9040, 0.8050, 0.7165, 0.5285 and 0.5335 mm at five different sites in immediate provisionalization group, and 0.8780, 0.8605, 0.7560, 0.5900 and 0.6300 mm, respectively, in delayed provisionalization group, showing no significant difference between the groups at all measurement sites. Although the labial contour changes of the two groups were similar at most sites, the values at 1 and 2 mm above the implant neck remained significantly lower in the immediate provisionalization group at three and six months postoperatively. No complications occurred during the follow-up time. Based on the limitation of this study, the immediate implantation combined with GBR, flap operation and immediate provisionalization obtained acceptable outcomes for a single anterior maxilla with vertical defect on the labial bone, but more long-term research with a larger sample are urgently needed in the future.

Palatal Bone

A 44-year-old male patient was referred to the Egas Moniz Dental Clinic, with a previous history of failed bone regeneration, resulting in a reduced buccal-palatal bone thickness and aesthetic compromise of the gingival margin of the anterior maxilla. Since the use of autologous bone is considered the “gold-standard” in guided bone regeneration, the treatment plan consisted of an autologous mental graft into the maxilla, with a simultaneous guided bone regeneration with a xenograft and absorbable membrane. This allowed a predictable volumetric bone regeneration with low patient morbidity and posterior fixed rehabilitation.

The aim is to describe bilateral vertical ridge augmentation with intraoral block grafts and guided bone regeneration in the posterior mandible in preparation for implant placement. A 61-year-old woman, edentulous in the posterior mandible, presented for implant rehabilitation. The radiographic study showed 3 to 6 mm of bone height from the ridge to the mandibular canal. Autogenous bone block grafts from the chin and the mandibular ramus, harvested with ultrasonics, were used to augment the alveolar ridge. To reduce resorption, the grafts were covered with particulate alloplastic material and a collagen membrane. Delayed implants were placed 6 months after vertical augmentation, and 3 months later implants were loaded with a fixed prosthesis. A temporary sensory complication occurred, but 12 months after implant loading, there were no failures. In this case report block bone grafting was a feasible option to vertically augment the alveolar ridge in the posterior mandible.

Abstract Insufficient width of the alveolar ridge often prevents ideal implant placement. Guided bone regeneration, bone grafting, alveolar ridge splitting and combinations of these techniques are used for the lateral augmentation of the alveolar ridge. Ridge splitting is a minimally invasive technique indicated for alveolar ridges with adequate height, which enables immediate implant placement and eliminates morbidity and overall treatment time. The classical approach of the technique involves splitting the alveolar ridge into 2 parts with use of ostetomes and chisels. Modifications of this technique include the use of rotating instrument, screw spreaders, horizontal spreaders and ultrasonic device. The purpose of this article is to thoroughly describe all the different approaches in ridge splitting technique. 2 interesting clinical cases of narrow alveolar ridges treated with ridge splitting and immediate implant placement are also presented.
