Georgia's 1991-92 President Zviad Gamsakhurdia, a persecuted human rights advocate in Soviet times, died in mysterious circumstances in 1993, aged 54, two years after being ousted and replaced by Eduard Shevardnadze and following a civil war.
It has still not been established whether he was assassinated or committed suicide.
"It's up to the family to decide whether a further examination will take place", Interior Minister Vano Merabishvili said.
After Mikheil Saakashvili became Georgian president in 2003, he rehabilitated Gamsakhurdia and released his supporters, imprisoned during Shevardnadze's rule.
For more than a year after his death, Gamsakhurdia's body was missing. It was recovered in February 1994 and reburied in Grozny, the Chechen capital, at his widow's request.
The remains of Gamsakhurdia were exhumed in Russia's North Caucasus republic of Chechnya March 3 and were recently sent to his family home in the center of Tbilisi, Georgia's capital, for reburial.
A law enforcement official said earlier this month that an examination of the remains revealed two holes in the skull, which might have been caused by bullets.
Mamuka Akhvlediania, the deputy mayor of Tbilisi said a preliminary examination has confirmed earlier this month that the remains were Gamsakhurdia.
"According to preliminary results, these are indeed the remains of the first [Georgian] president. We received the information from his younger son, Tsotne Gamsakhurdia, who is in Rostov," he said.
The president's son Tsotne Gamsakhurdia, whose trip to Grozny was organized by Russia, said he was sure the remains belonged to his father.
"I have no doubt that it is him. There was a cross, the Georgian soil, shoes and a watch in the coffin that we put in ourselves," he said.
On April 1, the remains of Zviad Gamsakhurdia will be re-buried in Mtatsminda Panteon, the country's cemetery for famous writers and public figures, according to the wishes of the family.
