Samy Elian, Khaled Barakat
Closed sinus lifting is a unique technique in being simple and less invasive (Summers, Compendium 15(6):698, 1994). However, it is blind to assess the safety of sinus lining during lifting without perforation. Previously, sinus membrane was assessed endoscopically in an invasive way. We aimed to judge clinically the sinus membrane integrity after crestal elevation by a direct simple less invasive endoscopic visual assessment through the crestal osteotomy site. To confirm undetected perforation, the sinus membrane was monitored dynamically by introducing the endoscope through a trephined opening in the lateral wall of the sinus (Nkenke et al...

T C Niño-Sandoval, B C Vasconcelos, S L D Moraes, C A A Lemos, E P Pellizzer
The aim of this review was to test the hypothesis of no difference in the efficacy of bone regeneration when using stem cells in maxillary sinus floor augmentation surgery in comparison to other grafts. Nine randomized clinical trials and one follow-up study involving human subjects were identified through a search of the PubMed/MEDLINE, Scopus, Cochrane, and Web of Science databases, supplemented by a hand search. No significant difference between groups was found for the implant survival rate, increase in bone height, marginal bone loss following implant placement, or new bone formation...

During a sinus lift procedure the main requirement in order to position an implant is to have a maxillary sinus floor cortical bone thick enough to guarantee a primary stability in the implant inserted. In this way, the healing process is facilitated and osseointegration of the titanium surface may occur simultaneously, thus reducing the waiting time for the engraftment of the implant into the body. Unfortunately, these conditions are not always present. Hence, the need of developing an alternative approach that could simultaneously allow to perform sinus floor elevation along with an implant placement...

This case describes the successful long-term outcome of a patient's treatment after a restorative failure occurred soon after delivery. The esthetic and restorative treatment has been successful for nearly a decade due largely to a careful, objective evaluation of all possible causes of the restorative failure. The treatment plan for the patient, who was assessed as high risk biomechanically and functionally, was carried out in the following phases: (1) an implant placement that required an osteotome sinus lift; (2) placement of feldspathic bonded veneers for the maxillary anterior teeth to minimize removal of tooth structure; (3) numerous core-supported restorations, with fixed partial dentures placed for teeth Nos...

Maxillary sinus antrolithisis is a rare finding. Conservative surgical removal recommended. In the patients that need to maxillary intrasinus augmentation and antrolith is observed in preoperative radiography, 2 options remain. First, doing Caldwell-luc surgery to remove antrolith and delayed open sinus lift. Second way is removing antrolith and concomitant intrasinus augmentation.The first way has 2 disadvantages: prolonged waiting period and difficulty of open sinus lift in sinuses with scar and fibrosis...

Pneumatization of the sinus is a common occurrence after extraction of maxillary posterior teeth. Implant procedures require a clinically acceptable level of bone to be present for implants to be placed in function. Residual bone with >4 mm of height can be managed using the indirect sinus lift procedure, whereas bone height <4 mm requires a direct sinus lift using lateral window approach. This clinical case report describes the use of autogenous core used to lift the membrane in conjunction with calcium phosphosilicate putty using minimal armamentarium, thereby avoiding the associated morbidity and complications associated with a direct sinus lift procedure...

This study aimed to compare the primary and secondary stability, measured by resonance frequency analysis (RFA), in implants of different lengths installed in areas submitted to maxillary sinus lift. Correlation between RFA and implant insertion torque was also assessed. Twenty implants of 9 and 11 mm were inserted in areas submitted to maxillary sinus lift. The insertion torque was measured by the Bien Air motor. Osstell, through RFA, determined the implant stability quotient (ISQ) 2 times: the day of implant installation (T1) and 90 days after implant installation (T2)...

Treatment of severe maxillary atrophy with implants has achieved important successes in recent years. The limit of implant insertion is related to inadequate bone quantity (i.e. height and width). Alveolar bone grafting, sinus lifting and major grafting via Le Fort I osteotomy have used in the past to restore bone volume prior of implant insertion. However successes do not always occur and a second stage surgery is necessary in most cases. Immediate loading cannot be performed in all grafted bone. In recent years a new treatment approach has been proposed by using zygomatic implants...

Replacement of missing teeth in the posterior maxilla is always a challenge for the treating implant surgeon as the posterior maxilla has several obstacles in the form of quality, quantity, the anatomy of the maxillary sinus, and inaccessibility. To overcome these deficiencies, several surgical procedures such as sinus lift, bone augmentation, tilted implants, short implants, and zygomatic implants were tried. Since these procedures have their own limitations, pterygomaxillary region provides us an excellent place for placement of implant and rehabilitation of posterior maxilla...
