Filter by:Evaluation the influence of the use of silane coupling agent application as a separate step versus application of silane or acid resistance silane containing adhesives on the clinical performance of repaired posterior resin composite restorations according to Modified United States Public Health Service (USPHS) criteria over one year.
The aim of the study is to compare one-year clinical performance of indirect restoration fabricated from nano hybrid composite CAD CAM blocks and ceramic blocks
Many patients suffer from badly decayed anterior teeth mostly in young age, causing esthetics and functional issues. This may be due to more than cause as fights, contact sports, accidents and falls. However; implant placement might not be the treatment of choice in some situations such as: medically compromised patients with absolute contraindications for implant placement or requiring extensive augmentation procedures, growing patients, patients with financial limitations, in addition to patients living in rural areas with no access for CBCT machines. Moreover, clinicians must be aware of cost-to-benefit ratios when attempting to recommend a specific treatment modality, especially in patients having financial limitations. Regarding the aforementioned conditions, surgical extrusion might be considered a cost-effective 'often overlooked' alternative compared to immediate single-tooth implant placement. Regarding healing time, cost, soft and hard tissue outcomes, surgical extrusion may be a good alternative yielding better soft tissue results as we preserve the natural tooth with the whole periodontium.
Many patients suffer from tooth substance loss as a result of fracture or decay of teeth situated in the esthetic zone. This might commonly occur with car accidents, sport injuries, falls or even fistfights. For those patients, most of the crown is lost and only the root remains, so there is no enough ferrule in order to restore the tooth with a crown. The most common treatment for those patients is immediate single-tooth implant. However, some problems may arise such as: high treatment expenses, the need for bone augmentation, the refill of the papilla to its normal position may be questionable in some implant cases, young growing patients, apprehensive patients, dental facilities and rural areas lacking cone beam computed tomography (CBCT) machines. Accordingly, orthodontic extrusion may be an alternative attempt to preserve the tooth by traction of the remaining root to create a sufficient ferrule effect to restore the tooth.
Many techniques have been proposed to prevent or rather minimize the labial bone resorption following extraction including guided bone regeneration techniques that has been attempted for many years now to preserve the alveolar ridge dimensions . Immediate implant placement, flapless implant placement, palataly positioned implants and even platform switching. However none of these methods were able to completely preserve the coronal part of the facial bone wall, and since the main reason of bone loss following extraction is the loss of the periodontal ligament, it seemed logical that root retention may affect the resorption process,The reason the root retention technique works in its different applications is due to the maintenance of the periodontal attachment including cementum, periodontal ligaments and bundle bone, this principle was used by Hurzeler in 2010 in a technique called socket shied technique.
Different types of post and core have been used for several years for restoring anterior endodontically treated teeth, but their preparations involve various risks such as: root perforation, root weakness and tooth fracture. The introduction of adhesive systems and conservative restorations, make it possible to reconstruct damaged anterior endodontically treated teeth with conservative restoration as endocrowns. The hypothesis of this trial is that E-max CAD endocrowns will show comparably equal clinical performance if compared to E-max CAD crowns retained with fiber reinforced composite post and core system when treating anterior endodontically treated teeth..
in the last years, dentistry is going to the concept of conservatism to preserve the most amount of tooth structure, so the evolution of new ceramic materials with invasive designs like (inlay- shaped and proximal box shaped) inlay retained bridge, the investigators can restore single missing posterior teeth with less invasive techniques and less rate of restoration fracture.
When restoring teeth with IPS Empress laminate veneers, fracture of restorations may occur. So, material with higher mechanical properties is required. Celtra Duo is a new material with glass ceramics infiltrated by 10% zirconia particles which increase the fracture resistance of the material.
The most frequent reason for failure of laminate veneers made of glass ceramics (feldspathic, leucite based and lithium silicate based ceramics) was fracture of the ceramic, Therefore, ceramic materials that have higher fracture resistance, especially for patients suffering from abnormal occlusion, are needed.
