Embolization for Arteriovenous Malformations in the Maxilla With Coils and Ethanol.

11 2022

DOI: 10.1016/j.joms.2022.07.139 PMID: 35988693

Maxillary arteriovenous malformations (AVMs) are uncommon, limiting comprehensive research into standard treatment protocols. This study evaluated the management, outcomes, and clinical safety of embo... In this retrospective case series, we enrolled a sample of patients with maxillary AVMs treated with embolization using coils with or without ethanol between June 2017 and July 2019. Coils were super-... Ten patients were included in the present study, including 4 men (40%) and 6 women (60%), with a mean age of 18.1 years (range, 10 to 36 years).

In vitro accuracy of digital and conventional impressions in the partially edentulous maxilla.

Nov 2022

DOI: 10.1007/s00784-022-04598-4 PMID: 35778534

This in vitro study compared the dimensional accuracy of conventional impressions (CI) with that of digital impressions (DI) in a partially edentulous maxilla. DIs were made by two intraoral scanners,... CI and both intraoral scanners were used to take 30 impressions of two identical reference models. CIs were poured with type 4 gypsum and the saw-cut models were digitized. The reference models simula... For DI, the largest deviations (176 µm for OC and 122 µm for PS) occurred over the cross-arch. For CI, the largest deviation (118 µm) occurred over the anterior segment. For shorter distances up to a ... The impression method affected the impression accuracy of a partially edentulous maxilla with prepared teeth. DI is recommended for scans up to a quadrant. Larger scan volumes are not yet suitable for... In contrast to conventional impressions, digital impressions lead to comparable or better results concerning scans up to a quadrant. Consequently, for larger scan volumes, several smaller scans should...

Intraosseous arterial alteration of maxilla influencing implant-related surgeries.

Sep 2023

DOI: 10.1007/s00784-023-05141-9 PMID: 37460902

To investigate the intraosseous arterial pathways and anastomoses in the alveolar aspects of the maxilla in order to better understand the arterial scattering pattern.... Eleven cadavers were selected for macroscopic intraosseous arterial analyses by corrosion casting. The red-colored acrylic resin was injected into the external carotid arteries. The specimens were kep... Vertico-oblique and horizontal intraosseous arteries and anastomoses between the greater palatine-, posterior superior alveolar-, and infraorbital arteries were detected. The vertico-oblique anastomos... The localization of intraosseous arterial anastomoses is critical in implant-related surgeries, predominantly to maintain proper circulation.... Based on vertico-oblique and transalveolar anastomoses, simultaneous buccal- and palatal flap elevation (particularly on the palatal side) should be avoided to minimize patient morbidity and intra- or...

Pterygoid and tuberosity implants in the atrophic posterior maxilla: A retrospective cohort study.

Aug 2023

DOI: 10.1016/j.prosdent.2023.06.007 PMID: 37481400

Rehabilitation of the partially or completely edentulous posterior maxilla using dental implants is a clinical challenge because of the presence of the maxillary sinus, as well as the low quality and ... The purpose of this retrospective cohort study was to evaluate the survival of tuberosity and pterygoid implants in patients with posterior maxillary atrophy.... A nonprobability convenient sample of patients who had received fixed prostheses on implants placed in the maxillary tuberosity or pterygoid regions was analyzed retrospectively. Demographic variables... A total of 119 patients had 183 pterygoid or tuberosity implants inserted. Most implants in the pterygoid region (71.5%) were Ø4.1 mm (87.4%) and 15 mm in length (60.1%). The most common prostheses we... The survival of the implants placed in the maxillary tuberosity and pterygoid regions was high in patients with posterior maxillary atrophy....
