Lateral alveolar ridge augmentation procedure using subperiosteal tunneling technique: a pilot study

Abstract

BackgroundIn this research article, we evaluate the use of sub-periosteal tunneling (tunnel technique) combined with alloplastic in situ hardening biphasic calcium phosphate (BCP, a compound of β-tricalcium phosphate and hydroxyapatite) bone graft for lateral augmentation of a deficient alveolar ridge.MethodsA total of 9 patients with deficient mandibular alveolar ridges were included in the present pilot study. Ten lateral ridge augmentation were carried out using the sub-periosteal tunneling technique, including a bilateral procedure in one patient. The increase in ridge width was assessed using CBCT evaluation of the ridge preoperatively and at 4 months postoperatively. Histological assessment of the quality of bone formation was also carried out with bone cores obtained at the implant placement re-entry in one patient.ResultsThe mean bucco-lingual ridge width increased in average from 4.17 ± 0.99 mm to 8.56 ± 1.93 mm after lateral bone augmentation with easy-graft CRYSTAL using the tunneling technique. The gain in ridge width was statistically highly significant (p = 0.0019). Histomorphometric assessment of two bone cores obtained at the time of implant placement from one patient revealed 27.6% new bone and an overall mineralized fraction of 72.3% in the grafted area 4 months after the bone grafting was carried out.ConclusionsWithin the limits of this pilot study, it can be concluded that sub-periosteal tunneling technique using in situ hardening biphasic calcium phosphate is a valuable option for lateral ridge augmentation to allow implant placement in deficient alveolar ridges. Further prospective randomized clinical trials will be necessary to assess its performance in comparison to conventional ridge augmentation procedures.

Evaluation of the Bone Regeneration Effect of Recombinant Human Bone Morphogenic Protein-2 on Subperiosteal Bone Graft in the Rat Calvarial Model

“…The sufficient alveolar bone height and width should be sufficient for dental implant installation [21]. The subperiosteal bone graft has been clinically performed as a subperiosteal tunneling technique in oral and maxillofacial surgery [18]. The subperiosteal tunneling technique involves making a subperiosteal space or pocket in the alveolar ridge via a small incision and dissection, and the bone substitute material is grafted under the subperiosteal space [22].…”

“…The subperiosteal bone graft technique is a minimally invasive bone graft procedure that uses the subperiosteal space [22]. The subperiosteal bone graft has been performed on the atrophic alveolar bone ridge for augmentation of the vertical or horizontal length by using various bone substitutes, such as bovine bone, hydroxyapatite, and allograft material [17,18,22]. The subperiosteal space is surrounded by the periosteum, which has a rich mesenchymal stem cell, progenitor cell, and cytokines to induce bone formation [19,37].…”

“…Subperiosteal bone grafting is a minimally invasive technique that has been performed in oral surgery for new bone formation in the atrophic alveolar bone [17]. The bone graft operation on the subperiosteal space or pocket in the alveolus shows a favorable result in new bone formation, and it regenerates enough bone to install dental implants [18]. Various bone substitute materials are used in subperiosteal bone grafts in the alveolus; however, the combined use of a bone substitute and rhBMP-2 has not been evaluated.…”

Comparison of in‐situ bone ring technique and tent‐pole technique for horizontally deficient alveolar ridge in the anterior maxilla

“…To reduce such loss of bone mass to a reasonable extent, several approaches for the augmentation of absorbed alveolar ridge have emerged over the years . Ridge augmentation for horizontal alveolar ridge deficiency, as one of the reliable methods to surmount the Cawood‐Howell class IV defect, is regularly achieved by applying guided bone regeneration (GBR) technique including the use of xenogenic bone substitute materials and an absorbable membrane.…”
