What is an anatomical landmark on the mandible?
The landmarks include the mandibular foramen, the inferior alveolar nerve, the mental foramen, the mental nerve, the lingual nerve, the incisive canal and the incisive nerve all of which are of particular interest to clinicians who are planning dental implant surgery.
What are anatomical landmarks in dentistry?
Landmarks of the oral tissues include the palate, tongue, cheeks and floor of the mouth. It is significant to recognize the normal appearance of these structures during an intraoral examination of the patient.
What are maxillary anatomical landmarks?
The maxilla is the upper dental arch that contains the maxillary alveolar process, the maxillary teeth and the maxillary sinuses. It sits on either side of the nasal cavity and below the orbits.
Which of the following landmarks are located by the midline of the mandible?
Genial tubercle – The genial tubercle is a spiny protuberance or prominence (sometimes two) of bone located in the midline on the lingual aspect of the mandible below the roots of the incisor teeth.
Why are anatomical landmarks important?
Summary. Early anatomic landmarks and their normal appearance on ultrasound serve as the basis for understanding normal fetal development as a function of gestational age and their pathologic conditions, which in a combined fashion will ultimately reflect on management (see Chapter 12).
Why anatomical landmarks play a big role in dentistry?
The landmarks of an edentulous jaw are grouped into limiting structures, supporting structures and relief area. These are the sites that will guide us in having an optimum extension of the denture so as to engage maximum surface area without encroaching upon the muscle actions.
Which anatomical landmark is important in impression for lower full denture?
The anatomy of the edentulous ridge in the maxilla and mandible is very important for the design of a complete denture. The consistency of the mucosa and the architecture of the underlying bone is different in various parts of the edentulous ridge.
What are the major landmarks of the maxilla?
Terms in this set (27)
- Alveolar Process. Forms the bone that supports the maxillary, and mandibular teeth.
- Infraorbital Foramen. (Foramen means opening) is just below the orbit on the maxillary bone.
- Maxillary Sinus.
- Maxillary Tuberosity.
- The Greater Palatine Foramen.
- Lesser Palatine Foramen.
- Mandible.
- Rami.
Where is the Hamular notch?
In dental prosthetic practice, a full maxillary denture base is extended over the tuberosity and rests on mucosa overlying the hamular notch, which is the area between hamulus and maxillary tuberosity.
What are some anatomical landmarks of bones?

Which of the following landmarks is useful when mounting films in the maxillary posterior area?
Which of the following landmarks is useful when mounting films in the maxillary posterior area? Floor of the maxillary sinus.
What are the anatomic landmarks present in a maxillary arch?
In a Maxillary Arch, following anatomic Landmarks are present; Incisive Papilla: It is a pad of fibrous connective tissue overlying the orifice of the nasopalatine canal. Significance:Stable landmark and gives its relation to incisive foramen through which the neurovascular bundle emerge and lie on the surface of bone.
Where is the labial vestibule located?
Labial Vestibule: It extends on both sides of the midline from labial frenum anteriorly to the buccal frenum posteriorly. It is bounded laterally by the labial mucosa medially by maxillary residual alveolar ridge. Reflection of the mucous membrane superiorly reflects the height. The area of mucous membrane reflection has no muscle.
What is the difference between a mandible and a maxilla?
THE TOTAL AREA OF SUPPORT FROM THE MANDIBLE IS SIGNIFICANTLY LESS THAN FROM THE MAXILLA. THE AVERAGE AVAILABLE DENTURE BEARING AREA FOR AN EDENTULOUS MANDIBLE IS 14cm2 , WHEREAS FOR EDENTULOS MAXILLA IT IS 24cm2. THEREFORE THE MANDIBLE IS LESS CAPABLE OF RESISTING OCCLUSAL FORCES THAN THE MAXILLA.
Is the mandible less capable of resisting occlusal forces than the maxilla?
THEREFORE THE MANDIBLE IS LESS CAPABLE OF RESISTING OCCLUSAL FORCES THAN THE MAXILLA. 3.
