Study Notes
Mandibular Growth
- Underdeveloped mandible growth occurs by increasing the height of the ramus through deposition on condylar cartilage.
- The alveolar process height increases with tooth eruption, facilitating proper dental alignment.
- Growth tends to complete for girls by age 17 and for boys by age 19.
- Notable mandibular changes include increases in length and width, along with deposition on the mental protuberance.
Maxillary Growth
- The pre-maxilla experiences protrusion during growth.
- Maxillary growth occurs at maxillary sutures, directing movement downwards and forwards.
- The maxillary alveolar process grows simultaneously with tooth eruption.
- Growth completion typically occurs for girls by age 15 and boys by age 17.
Dental Fractures
- Concussion refers to an injury where the tooth remains displaced.
- Subluxation indicates increased mobility in the tooth.
- Intrusive luxation involves the tooth being pushed inward, while lateral luxation displaces the tooth sideways.
- Avulsion signifies total detachment of the tooth from its socket.
Factors Influencing Fractures
- Influencing factors include medical and dental history, resilience of the tooth, and the nature and direction of the applied force.
Types of Fractures
- Coronal Fracture: Results from high mass and velocity impact.
- Tooth Fracture: Occurs from low mass and velocity impact.
- Comminuted Fracture: The bone is broken in multiple places.
- Compound/Open Fracture: Bone penetrates the skin.
- Transverse Fracture: Straight break across the bone.
- Greenstick Fracture: An incomplete fracture often seen in children.
- Oblique Fracture: Break occurs diagonally across the bone.
Principles and Types of Splints
- Splints are designed to support damaged tissue, optimize healing, minimize ankylosis, and provide fixation for hard tissue injuries.
Soft Splint
- Advantages: Maintains oral hygiene and allows easy access for follow-up.
- Disadvantages: Provides insufficient support and requires impressions and lab work.
- Uses: Ideal for minor subluxations and to protect from additional trauma.
- Design: Extends over alveolar mucosa and is not cemented.
Hard Splint
- Advantages: Offers strong support for injured areas.
- Disadvantages: Also requires impressions and lab work.
- Uses: Suitable for luxation of single or multiple alveolar teeth.
- Design: Made of polycarbonate, trimmed to the gingival margin, cemented with relief around teeth for adjustments.
Edentulous Patients
- Gunning splint or converted denture is utilized for support and stabilization in edentulous individuals.
Requirements for Splints and Sports Guards
- Essential criteria include biocompatibility, comfort, retention, speech and airflow allowance, easy fabrication, durability, and resilience.
- Success factors encompass accurate impression taking, model fabrication, effective thermoforming techniques, and precise finishing of the design.
