Understanding Implant Abutments Dr. Shamsuddin Mahmud BDS, MS (Prosthodontics) Assistant Professor (cc) Department of Prosthodontics What is an Implant Abutment? An implant abutment is the transmucosal component that connects the implant fixture and the mouth. Driver handling Surgical Stages and Healing Abutments Connect Healing Abutment Soft and Hard Tissue Recovery Final Abutment Selection Final Connection Preparation Selecting the Right Healing Abutment ensuring it exposes 1-2mm above gingival. The diameter of the healing abutment should be similar to that of the final abutment. Inter-Occlusal Space Diameter Considerations Using a height over 5mm is recommended to avoid issues with short healing abutments being stuck on bone or pressed by gingival. Select a healing abutment that can later expand to fit the final abutment, ensuring proper alignment and integration with surrounding tissues. Height Recommendations Final Abutment Fit Avoiding Complications Improper connection can occur if the healing abutment is too short or too wide, causing it to be stuck on bone or pressed by gingival. Ensure to use healing abutments over 5mm height to prevent invading biologic width and causing undesired bone resorption and prei-mucositis. The locking phenomenon may arise if foreign body or blood remains inside the fixture during connection; thorough cleaning with saline and suction is necessary. Connect the healing abutment with a Hex driver for hand at a torque of 5~8Ncm to ensure proper attachment. Abutment Abutments Screw & Cement Retained Prostheses (SCRP) This approach combines the advantages and reduces the disadvantages of both cement-retained and screw-retained types, making it a vital solution in modern prosthetic applications. Advantages of SCRP It is most compatible with external connections, making it a preferable choice in many clinical situations. SCRP addresses issues such as 'mesial proximal contact loosening' and 'fracturing of porcelain', which are common complications in traditional prosthetic methods. 1 SCRP combines the advantages and reduces the disadvantages of both cement-retained and screw-retained prostheses, enhancing overall performance. Crown height space The interarch distance is defined as the vertical distance between the maxillary and mandibular dentate or dentate arches under specific conditions (e.g., the mandible is at rest or in occlusion).

Hypophosphatemia Causes Of Tooth Loss CARIES/ TOOTH DECAY Causes Of Tooth Loss CAUSES OF TOOTH LOSS Consequence of tooth loss Anatomic Loss of ridge volume both height and width Bone loss : mandible > maxilla Posteriorly > anteriorly Anatomic consequences Broader mandibular arch with constricting maxilary arch Attached gingiva is replaced with less keratinised oral mucosa which is more readily traumatized. Anatomic consequences Tipping of the adjacent teeth Supraeruption of the teeth Traumatic occlusion Premature occlusal contact Anatomic Consequences Anatomic Consequences Physiologic consequences Physiologic Consequences Decreased lip support Decreased lower facial height Physiologic Consequences Physiologic consequences Education of Patient Diagnosis, Treatment Planning, Design, Treatment, Sequencing, and Mouth Preparation Support for Distal Extension Denture Bases Establishment and Verification of Occlusal Relations and Tooth Arrangements Initial Placement Procedures Periodic Recall Education of Patient� Informing a patient about a health matter to secure informed consent. Patient education should begin at the initial contact with the patient and should continue throughout treatment. The dentist and the patient share responsibility for the ultimate success of a removable partial denture. This educational procedure is especially important when the treatment plan and prognosis are discussed with the patient.

Exophytic angular formation of osseous tissue arising from the surface Subcortical sclerosis Any increased thickness of cortical plate in load‐bearing areas relative to adjacent non‐load‐bearing areas Subcortical cyst A cavity below the articular surface that deviates from normal marrow pattern Surface erosion Loss of continuity of articular cortex Articular surface flattening A loss of the rounded contour of the surface General sclerosis No clear trabecular orientation with no delineation between the cortical layer and the trabecular bone that extends throughout the condylar head Transcranial view CBCT Three-dimensional shape and internal structure of the osseous components Surrounding some soft tissue Both axial & coronal images Reformat images in sagittal plane Ideal for the evaluation of fractures, degenerative changes, erosions, infection, invasion by tumor, as well as congenital anomalies Not diagnostic for disk MRI Images in the sagittal and coronal planes without repositioning the patient T1-weighted images best –osseous & diskal tissues T2-weighted images-inflammation and joint effusion. Motion MRI studies-during opening and closing the patient open in a series of stepped distances and using rapid image acquisition. ("fast scan ") In the coronal plane The disk is crescent shaped and Its medial and lateral borders are attached to the respective aspects of the condylar head and joint capsule. conclusion Imaging of TMJ should be performed on a case by case basis depending upon clinical signs and symptoms. MRI is the diagnostic study of choice for evaluation of disk position and internal derangement of the joint. CT scan for evaluation of TMJ is indicated if bony involvement is suspected and should be judiciously considered because of radiation risk. Understanding of the TMJ anatomy, biomechanics, and the imaging manifestations of diseases is important to accurately recognize and manage these various pathologies. ]]>
