Digital Framework RPD Design for the Patient with
Non-free-End Deletion
1. Before restoration
A woman, 76 years old.
Face analysis: The nasolabial groove is deep and the
corner of the mouth is upward.
Smile analysis: The patient has a middle smile line as
well as deep overbite (Fig.6.84), and the esthetic teeth
are A4–B4 (Fig.6.85).
Dentition analysis: The cervical gingivae of the entire
mouth recede and the roots are exposed. Furthermore, the
overbite and overjet of anterior teeth are deep. C6, D6, and
D7in the mandibular are dental implants. Missing teeth
are A4, A5, B6, and B7. Besides, A6 is I°loose, and the
remaining teeth all have appropriate undercuts (Fig.6.86).
We put e-clasps on A3, A6, B5, and B8 (Fig.6.87).

2. RPD analysis design and manufacturing
Framework design: A short buccally retained clasp
and a lingual rest are placed on A3, three-arm clasps are
put on A6 and B8, and a C clasp is designed on B5. We
consider two designs of the major connector in the palate:
posterior palatal bar or U palate plate (Figs. 6.88 and
6.89). Combined with the patient’s oral condition and
comfort, we choose the posterior palatal bar (Fig.6.90).
Trying in of the framework is shown in Fig.6.91.
3. After restoration
The nal restoration is shown in Figs.6.92, 6.93, and
6.94. The patient is contented.
