Case study questions Flashcards
Female patient lost a tooth and wanted a fixed replacement. She previously had a large restoration on the missing tooth before extraction and prefers a minimally invasive approach but long-term function is important. The missing tooth is the 12 (upper right lateral incisor), with the 11 being healthy, has sufficient enamel and a mild mesial tilt, and the 13 is strong, well-supported and ideal for load-bearing. There is no signs of periodontal disease and has good bone support. Based on clinical findings, discuss the most appropriate type of dental bridge for this patient.
13 is strong enough to act as single abutment. Cantilever bridge minimises unnecessary preparation of 11.
A 60-year-old male presented with a missing tooth and wants a fixed replacement that won’t damaged his other teeth too much. The missing tooth had a previous large filling prior to extraction and prefers a conservative option with minimal tooth preparation. The missing tooth is the 36, with the 35 health, with intact enamel and minor mesial drift. The 37 is also healthy, strong and is slightly tilted mesially. He has no periodontal disease and has adequate bone support.
Based on the clinical findings, discuss the most appropriate type of dental bridge. Consider the advantages, disadvantages and potential complications of each bridge type before justifying the final selection.

A 45-year-old patient presents with a missing 11. The patient desires a highly aesthetic solution and has sufficient soft tissue volume. Which pontic design would be the most appropriate. Justify your answer by discussing both aesthetic and functional considerations.
.
Explain the importance of tissue contact in pontic design and how it influences the selection of pontic types.
.
Compare and contrast the conical pontic and the ovate pontic, mentioning aesthetics and hygiene considerations.
.
What are the key features of a hygienic (sanitary) pontic, and in which clinical situations is it commonly used for?
.
A 55-year-old female patient present with a missing 46. She lost the tooth due to periodontal disease but now has stable periodontal health. She requests a fixed prosthesis and emphasises that she wants something easy to clean as she struggles with flossing. Adjacent teeth – 45 and 47 are health and can serve as abutments. Moderate ridge resorption is present in edentulous area. Oral hygiene is average, with some difficulty cleaning posterior area.
Based on findings, which type of pontic design would be most appropriate for this patient?
a) Identify and describe the best pontic design for this case.
b) Justify the choice by discussing advantages in terms of hygiene, function and long-term prognosis.
c) Explain why other pontic designs may not be suitable for this case.
d) Discuss any modifications or additional considerations that could improve the final prosthetic outcome.
.
A 40-year-old male presents with a missing 12. He lost the tooth due to trauma and is highly concerned about the aesthetic appearance of his smile. The patient has health adjacent teeth – 11 and 13 with minimal ridge resorption. He requests a fixed replacement that looks as natural as possible.
Based on findings, which type of pontic design would be most appropriate for this patient?
a) Which pontic design would be the most appropriate for this patient?
b) Justify the selection by discussing the advantages in terms of aesthetics, function and soft tissue adaption.
c) Explain why alternative pontic designs would not be suitable for this case.
d) What modifications might improve the final aesthetic outcome?
.
A 52-year-old male presents with a missing 14. He lost the tooth 10 years ago, and the ridge has significantly resorbed, leaving a concavity in the edentulous space. He is concerned about the function and appearance but prefers a minimally invasive solution without surgery.
Based on findings, which type of pontic design would be most appropriate for this patient?
a) Which pontic design would best accommodate the patient ridge resorption while maintaining acceptable aesthetics?
b) What challenges does ridge resorption present when designing a pontic, and how does the chosen pontic address these challenges?
.
A 25-year-old female presents with a missing 41 due to a sports injury. She has intact and health adjacent teeth 31 and 42 with a good bone support. She prefers a non-invasive option and is concerned about preserving her natural teeth.
Based on findings, which type of pontic design would be most appropriate for this patient?
a) Which pontic design would be the most conservative and effective for this patient?
b) What are the advantages of this pontic design in terms of tooth preservation and function?
c) Why would a fixed-fixed bridge pontic not be ideal in this case?
d) Discuss potential limitations of your chosen pontic design and how they can be managed.
