Filter by: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.
Immediate implant placement (IIP) has been an attractive treatment concept for both patients and clinicians due to reduced surgical interventions and total treatment span. Although soft-tissue alterations or midfacial recession have been demonstrated in previous studies, recent studies have reported positive result following IIP with the modification of surgical interventions. However, high-quality evidence (≥Ib: evidence from at least one randomized controlled trial) on comparing the clinical outcome of IIP with early implant placement (type 2) is limited.
This investigation will be a clinical trial to study the performance of a new resin-based ceramic material for crowns. The material has been approved by the FDA for patient treatment. A computer technique will be used to fabricate the crowns in a single appointment without the need for a temporary crown or second appointment. The purpose of the study is to measure how well the high strength crowns function over an extended period of time.
The present study aims to evaluate the clinical outcomes of immediate implant placement with connective tissue graft or socket shield. Previous studies have demonstrate the intact buccal bone plate plays an important role in the stability of peri-implant soft tissue around immediately placed implants. However, it remains controverisal whether soft tissue stability could be achieved in immediate implant placement with connective tissue graft or socket shield.
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..
Total of 48 subjects were randomly assigned to treatment groups: UT Health Science Center at San Antonio Chi Mei Medical Center, Tainan, Taiwan Patients require a maxillary non-molar extraction site that is planned to be replaced by a dental implant and crown. This includes Straumann BL SLActive: Narrow (3.3mm) & Regular (4.1mm) Crossfit implants in all available lengths. Patients were randomly selected to receive either FDBA (test) or Autogenous bone + DBBM (control/standard) for contour augmentation.
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.
The aims of this clinical study are: To evaluate the clinical performance between indirect composite and ceramic laminate veneers: Main interests are: - colour stability of the restoration (digital measurement in follow up) - failure mode of the restoration - wear of the restoration and antagonist Hypothesis: - The colour stability of indirect composite restorations will not be different from the ceramic restorations. - The indirect composite restorations will not be more prone to failure than the ceramic restorations. - Antagonist wear and restorative material wear will be similar for both ceramic and composite. Material and Methods The laminates will be fabricated according to a specified protocol. In order to avoid possible noticeable differences in case of distinct levels of possible discoloration, a modified split mouth design is employed where the central incisors and the symmetric other teeth receive the same type of restoration. Randomization is based on the paired teeth and it is performed using the flip of a coin for the choice of material. Evaluation will be performed at baseline and at follow-up visits annually up to 2 years.
