science & practice 25th EAO Annual Scientific Meeting 16 n Implant dentistry has developed further over the last several years as a result of patient demand for aes- thetic treatment. Augmentation of hard and soft tissue is increasingly necessary to achieve good aesthetic results and to follow a precise back- ward treatment plan. Nowadays, guided bone regeneration, the use of a barrier membrane that will sepa- rate and protect the grafting material covered by a flap, is the preferred technique among all augmentation procedures in the treatment of alveo- lar ridge defects. At aesthetics ONE dental studios, we recently conducted a study based on our clinical cases. The purpose was to determine whether a ridge augmentation procedure using a re- sorbable collagen membrane deliber- ately left open to heal, that is not cov- ered by a flap (open healing), could be an alternative for better bone preser- vation and new bone formation. We also wanted to establish whether it would increase patient comfort in daily practice compared with the classic guided bone regeneration pro- tocol. For the study, radiographs, CBCT scans and measurements were taken preoperatively, immediately postop- eratively, as well as after six and 12 months, in order to determine the bone preservation and formation at each point and to integrate the re- sults with the clinical outcome. We found that the bone volume was pre- served in height and width for an ideal second-stage flapless implant placement after six months with bone preservation of 98.9 ± 0.7 % compared with initial measurements. In all of the cases we performed bone grafts without deperiostation and flap mobilisation, covering the augmented area from the beginning with only a resorbable collagen mem- brane and suturing it to the wound edges in order to fix it in a stable po- sition using a PTFE suture (Coreflon, Implacore). We followed the same procedure for both aesthetic and pos- terior zones. Owing to its unique properties, the PTFE suture contrib- uted to adequate tissue healing with minimal micro-damage reaction and bacterial colonisation. It also in- creased patient comfort by very good adaptation to the volume of tissue in all its healing stages. We therefore consider the use of a continuous su- ture with Coreflon the gold standard in the open healing protocol. 7 Open healing protocol An alternative ridge augmentation procedure for implant patients.
